Did you know Düsseldorf Airport's first modern Master Plan envisaged up to six runways? Read all about it below!

Düsseldorf International Airport is Germany's third busiest airport after Frankfurt and Munich. In 2019, the airport handled over 25 million passengers.

Despite having a larger catchment area than Frankfurt and Munich, the airport's development potential has been limited.

Düsseldorf has two parallel runways. However, the runways are close to each other and cannot be used independently. In addition, use of the parallel runway is capped due to political restrictions.

Things could have looked very much different...

A MIDFIELD TERMINAL COMPLEX

In 1952, two years after Düsseldorf Airport had been returned to civil authorities, the airport asked NACO Netherlands Airport Consultants B.V. to prepare a Master Plan for the airport's long-term development.

As shown in the images below, NACO envisaged that an entirely new passenger terminal complex would be built north of the main runway. Later on, a new independent parallel runway would be built, putting the new passenger terminal at the heart of the airport.

The above artist's impression shows a possible layout of the midfield terminal, indicating a linear mile-long boarding concourse with aircraft parked on either side under an overhead canopy, and what looks like a headhouse or processor located at the bottom left.

The concept is really very contemporary for 1952 and is reminiscent of the once planned Westside Terminal at DFW. The current passenger terminal is located where the four hangars are visible (left).

SIX RUNWAYS

​​Finally, as shown above, a fourth runway--which somehow looks like Düsseldorf's version of FRA's Startbahn West--would be added, providing the airport with two pairs of parallel runways. 

But it didn't stop there. As shown below, the plan had a provision to add two more runways, raising the total number of runways to six.

​One of the main runways could be lengthened to over 15,000 feet (4,500 meters)--an amazing length even now, let alone in the days before jets!

However, instead the airport chose to further develop the south side of the airport.
A second parallel runway opened in 1992 but was built close to the existing runway. In order to get it built concessions had to be made restricting its use.

And the rest as they say is airport history!

What if these plans would have been executed? Could Düsseldorf Airport have played a much more prominent role in Germany and Europe than it does today?

Following last week's very popular Memphis post, we want to share some more very rare images with you, this time of Portland International Airport in 1963.

They were part of the same batch as the Memphis images. This time it concerns all exterior shots. There is relatively little historical material on "PDX" out there from the early days--let alone in full color--with the exception of the obligatory postcard.

Even if it's just a few images, they are so unique that we thought it was worth a little standalone post. Now, let's have a look! You can click the images to enlarge.

An exterior view of Portland's terminal building, which opened in 1959. The terminal cost USD 4.25 million and  took two years to build.

A view of the airport parking lot taken from the airport control tower. Parking was a breeze in those days!

A ramp view looking toward the terminal building. A Northwest DC-4 is parked at the concourse. Other major operators at PDX were United Airlines, Western Airlines, and West Coast Airlines, the last of which served local feeder routes. I just love those ramp lights!

A view of the northern concourse, which was used by United Airlines. Later on in the 1960s the concourses were fitted with boarding bridges.

We end with this view looking west toward the southern concourse. This concourse was completely rebuilt in 1973.

We hope you enjoyed these vintage images of Portland Airport. There's a LOT more where that came from so make sure you sign up for the newsletter to know when new content goes online!

During our recent digs in the AirportHistory.org archives, we stumbled upon a  batch of amazing images of Memphis Airport's brand new Jet-Age terminal, taken shortly after its opening in 1963. Better still, most of the images are in full color!

For this blog post, we want to show you a selection of these ultra-rare images. Now, without further ado, let's go back in time and explore Memphis Airport in 1963!

A fantastic interior view of Memphis Airport's brand new terminal building, looking toward the airline ticketing desks. The terminal was inaugurated on June 7th, 1963. On the occasion, Memphis Municipal Airport was renamed Memphis Metropolitan Airport. In 1969, it was renamed Memphis International Airport.

An exterior view of the new terminal looking south. It was designed by Memphis-based architect Roy Harrover and cost USD 5.5 million to build. The original plan had provisions for additional terminal modules to the left and right of the main building. These were built in the early 1970s along with new boarding concourses.

The modern and stylish Delta Air Lines ticketing desk. The six other airlines that served Memphis in 1963 were: American, Braniff, United, Eastern, Southern and Trans-Texas--the latter two being local service carriers.

A few passengers are waiting for their flights. The Coke slogan is very apt for an airport terminal. 

An exterior close-up view of the terminal, whose design was notable due to its distinctive martini glass-shaped columns. How appropriate a theme for the early Jet-Age! 

An aerial view taken looking south. The main part of the "Y"-shaped boarding concourse boasted seven gates equipped with boarding bridges. The two upper sections of the "Y" concourse featured simple, single-level structures with an another 15 gates. Note that all visiting aircraft are propeller aircraft. In 1963, Memphis Metropolitan Airport handled just over 1 million passengers.

The American Airlines ticketing desk.

As this enlargement of the flight schedule shows, American was a sizeable player in Memphis in the days before deregulation. 

The Memphis Airport terminal was one of the first airport terminals that separated arrivals and departures on different levels.

A model of the terminal which is displayed inside the terminal building. It even has little lights inside.

Looking toward the boarding concourse. Contrary to nowadays, boarding concourses in those days were mere corridors, containing just some seats. All commercial facilities were located in the main building.

Last but not least--an American Airlines Boeing 707-120 pulls up to Gate 1. Memphis was one of the first airports in the US that was designed with jets and boarding bridges in mind. The gentleman up on the roof terrace is getting quite the view!

We hope you enjoyed our little glimpse of Memphis Airport in 1963! We will soon be offering a selection of these images as well as interesting documents pertaining to Memphis Airport's history as high-quality downloads in the AirportHistory Digital Library.

Did you know that the AirportHistory.org archive not only contain amazing images, but also airport traffic statistics going back to the earliest years of commercial aviation?

Today, we present you a snapshot of the world's 10 busiest airports 60 years ago in 1961, at the dawn of the Jet Age!

10. New York LaGuardia Airport

In 1961, New York's LaGuardia Airport handled 3.3 million passengers, ranking the city's domestic airport as the tenth busiest airport in the world.

In 1961 LaGuardia was still operating from the original 1939 terminal building. The following year, work would begin on phased construction of a new terminal on the same site, which opened in 1964.  History is repeating itself today as the 1964 building is being replaced piece by piece by a much larger new terminal

In 2019, LaGuardia handled just over 30 million passengers, putting it at 21st place in the United States and 71st in the world.

9. Chicago Midway Airport

Chicago Midway Airport was the world's busiest airport in terms of passenger traffic until 1959, when it handled just over 10 million passengers, a huge number for that time period! However, due to the limited length of the runways, Midway was unsuitable for the first generation of jets, such as the Boeing 707 and DC-8.

Thus, in 1960 the transfer of traffic to the newly expanded Chicago O'Hare began and traffic at Midway started to decline. That year, the airport handled 6.9 million passengers. In 1961, traffic at Midway reduced to 3.6 million passengers, which still lands it a place in the top 10 of that year.

After laying empty for a number of years, traffic at Midway slowly recovered, and in 2019, the airport handled 20.8 million passengers, ranking it 28th busiest in the United States and 127th in the world.

8. Atlanta Municipal Airport

In 1961, Atlanta Municipal Airport handled 3.8 million passengers, ranking it the eighth busiest in the world.

In May of that year, Atlanta opened its new Jet-Age terminal, allowing the airport to fully leverage its favorable geographic location and develop into one of country's primary connecting hubs.

In the following decades Atlanta, now called Hartsfield-Jackson International Airport, would steadily climb up the ranks. In 1998, it became the world's busiest airport in terms of passenger numbers, a position it has held until today. In 2019, Atlanta Hartsfield-Jackson Airport handled a whopping 110 million passengers.

7. Miami International Airport

Miami International Airport has traditionally functioned as the US gateway to Latin America. In 1961, Miami handled 4.1 million passengers making it the seventh busiest airport in the world at the time.

​Miami's new terminal was only two years old in 1961 and was expanded that year with the addition of a sixth concourse (today's Concourse H)."

In 2019, Miami handled 45.9 million passengers, ranking it 16th in the US and 45th busiest in the world.

6. Washington National Airport

In 1961, Washington National Airport handled 4.7 million passengers making it the sixth busiest airport in the world. 

Due to its constrained location National was not able to expand. In 1962 Washington Dulles Airport was opened to accommodate the cities long-term needs.

Through the years National, now called Ronald Reagan Washington National Airport, dropped in the rankings. In 2019, the airport handled 24.8 million passengers, ranking it 26th in the United States and 117th in the world.

5. San Francisco International Airport

​In 1961, San Francisco International Airport handled 5.2 million passengers making it the fifth busiest airport in the world that year.

San Francisco's runway layout is not conducive to hub-and-spoke operations and in the 1980s "SFO" dropped out of the world's top ten.

However, due to the tech boom in the 1990s, San Francisco again entered the top ten even becoming sixth busiest in the world. In 2019, the airport handled 57.5 million passengers, ranking it seventh busiest in the US and 23rd busiest in the world.

4. London Airport (Heathrow)

London Airport, as Heathrow was called back then, handled 6.3 million passengers in 1961 making it the fourth busiest in the world and the only airport outside the United States to make the top 10!

In 2019, Heathrow handled over 80 million passengers, ranking it seventh busiest in the world. 

​Read about Heathrow's early runway layout here.

3. Los Angeles International Airport

In 1961 Los Angeles International Airport opened its massive new Jet-Age terminal complex. That year, "LAX" handled 7 million passengers, ranking it third busiest in the world. 

In 2019, it handled just over 88 million passengers, again ranking it third busiest in the world after Atlanta Hartsfield-Jackson and Beijing Capital Airport, and second busiest in the United States behind Atlanta Hartsfield-Jackson International Airport.

Explore the LAX 1960s Jet-Age terminal here.

2. Chicago O'Hare International Airport

In 1961, Chicago O'Hare Airport handled 9.6 million passengers, ranking it second busiest in the nation. In 1962, the transfer of traffic from Midway to the expanded O'Hare was completed. That year O'Hare became the busiest airport in the world, a title the airport would retain until it was overtaken by Atlanta in 1998.

In 2019, the airport handled 84.7 million passengers ranking it sixth busiest in the world and third busiest in the United States, behind Atlanta and Los Angeles.

1. New York International Airport (Idlewild)

Due to the transfer of traffic between Chicago Midway and O'Hare, New York's Idlewild Airport, now John F. Kennedy Airport, temporarily became the busiest airport in the world in both 1960 and 1961. In 1961, Idlewild processed 10.2 million passengers.

In 2019, Kennedy Airport handled 62.6 million passengers ranking it sixth busiest in the nation and 20th busiest airport in the world.

A FEW NOTES ON METHODOLOGY

It needs to be stated that in the 1960s there was not yet a standardized methodology among airports and airport authorities for keeping statistics. Data from different sources often have different numbers and sometimes transit traffic is included or not. Where possible, we relied on data directly supplied by the airports. As we have at least two sources for all numbers, we are confident the above presents a reliable picture.​

Data for airports in the former USSR for 1961 is unavailable. Statistics for Chinese airports were not kept at the time.

​Aircraft taxiway bridges and runway bridges are designed to carry taxiways and runways over major roads, railways and even waterways.

They are ubiquitous nowadays but in the 20th century they were a rarity only to be found at a handful of major airports.

Designed to carry the heaviest aircraft of the day, as well as those of the future, they were--and still are--amazing feats of engineering. 

Let's have a look at some great images of early aircraft bridges around the world! 

1. New York's "Idlewild" Airport (later Kennedy Airport)

A Pan American Boeing Stratocruiser taxies on the aircraft bridge over the Van Wyck Expressway at New York's Idlewild Airport--later Kennedy Airport--in 1950.

Completed the year prior, the bridge was the first aircraft bridge in the world. Read more about the early years of Idlewild/Kennedy Airport. Or see an overview of all JFK Airport articles.

2. Los Angeles International Airport (LAX)

A 1953 view of the newly-completed Sepulveda Boulevard Tunnel, which runs underneath the southern parallel runways of LAX. The tunnel was the first in the United States to run under an airport runway.

​For more vintage LAX, have a look at our LAX 1960s photo special.

3. Heathrow Airport

Also completed in 1953 was the road tunnel underneath London Heathrow Airport's runway 09L/27R, which provided access to the newly-built Central Terminal Area.

This view looks south towards the northern tunnel entrance. The four-lane tunnel included two separate lanes for bicycles and pedestrians. Only in Europe!
London Heathrow's Central Terminal Area became operational in April 1955.

Read about Heathrow's original runway layout.

4. Paris Orly Airport

A view of the motorway passing underneath Paris Orly Airport, taken ca. 1960. Not to be outdone by the Brits or the Americans, the Orly tunnel not only passed underneath the runway but also the main apron and the terminal building. 

In 1966, construction started on a major motorway tunnel underneath the runway of the new Paris de Gaulle Airport. Read more about the design and construction of "CDG".

5. Denver Stapleton Airport

In 1962, Denver Stapleton Airport became the first US airport with an aircraft bridge over a major Interstate Highway (I-70). The bridge carried Stapleton's runway 17/35 (later 17R/35L).

6. Toronto Pearson Airport

Toronto Pearson's circular "Aeroquay 1" (1964) was built as an island in the middle of the apron to optimize aircraft circulation. Passengers reached the terminal via a tunnel underneath the apron.

Read more about Pearson and the early plan to replace the Aeroquay.

7. Chicago O'Hare Airport

In 1966, Chicago O'Hare Airport--then the busiest airport in the world--got its first aircraft bridge.

Crossing the Kennedy Expressway connecting O'Hare with downtown Chicago, the bridge provided a direct connection between the terminal area and the thresholds of runways 27 and 32R.

8. Amsterdam Schiphol Airport

A KLM 747-206B is taxiing over the Amsterdam-The Hague-Rotterdam Motorway on her way to runway 01L/19R (now 18C/36C), in the summer of 1972.

The bridge was completed in 1967. A bit further to the north is an aircraft tunnel that carries Schiphol's runway 09/27.  If you look carefully you can see the tunnel entrance in the image.

​See more great vintage images of KLM 747s at Schiphol. Ever wondered about the Schiphol's runway in the middle of nowhere? Read all about it.

9. Sydney Airport

The tunnel underneath Sydney Mascot's runway 16/34 (now 16R/34L) was built to accommodate the runway's extension into Botany Bay. Opened in 1967, it was the first aircraft bridge outside Europe and North America.

10. Dallas/Fort Worth Airport

"Everything is bigger in Texas," as the saying goes. When the massive Dallas/Fort Worth Airport opened in 1974, it boasted four taxiway bridges. The bridges cross International Parkway, the access road that bisects the airport.

Read about a never-built plan to demolish DFW's semi-circular terminals, replacing them with mile-long linear concourses.

BONUS: Singapore Changi Airport

Singapore Changi Airport opened in 1981. It boasted an aircraft bridge over the airport approach road, making it the second aircraft bridge in the Asia-Pacific region after Sydney.

The third one would be opened the year after, when the long-delayed Kai Tak Tunnel opened underneath Hong Kong Kai Tak Airport's apron and runway.

BONUS: Another photo from Denver Stapleton

For our last photo, we revisit Denver Stapleton's I-70 bridge a few decades later, ca. 1990, carrying a majestic United Airlines 747.

On September 21st, it will have been 40 years ago that Atlanta's Midfield Terminal Complex opened for traffic.

Its characteristic layout of long concourses, perpendicular to the runway and connected by an underground people mover system, ensured a highly efficient movement of both passengers and aircraft. For the decades that followed, Atlanta would become the gold standard for the design of hub airports.

However, did you know that the design evolved from a plan that was very similar to the original plan for Dallas/Fort Worth Airport? It's only due to project delays that we got the the "ATL" we know today. Read all about it below!

THE NEED FOR A NEW TERMINAL

Atlanta's previous terminal was completed in 1961. It was originally designed for 13.5 million passengers, a level that was already reached in the mid-1960s.

In 1967 the city decided it was time to build a new terminal and modify the existing one. In November 1967 a consortium of architects commenced the difficult task of designing the world's largest air passenger terminal building.

Everyone--the airlines, the two participating joint venture planning firms and even airline pilots--submitted ideas for the terminal design. The architects compiled sixty concepts into a briefing book. Those were narrowed down to ten for a more detailed study. 

INSPIRATION FROM TEXAS

In the late 1960s the primary consideration in airport design was passenger convenience in the form of short walking distances between parking facilities and aircraft gates.

In December 1967, the master plan for the newly planned Dallas/Fort Worth Regional Airport was published. Prepared by Walther Prokosch, who also designed the original Pan Am terminal and the Worldport expansion, the plan proposed the concept of 20 self-contained terminals along a connecting roadway. 

Airlines praised the model. They loved the idea of operating their own airport facilities and the small airport convenience the "mini-terminals" brought.

Thus, the Atlanta architects developed their own version of the DFW plan. They conceived the midfield complex as a series of sixteen terminal units along structural, double-decked roadways of Interstate 85 on the west. The roadways met on the east side and continued at ground level to Interstate 75.

Each terminal was self-contained with aircraft gates, ticketing and baggage facilities. The 600-foot (183-meter) central strip was dedicated to roadways and parking garages. A people mover system ran through the upper level of each terminal, parallel to the roadways. Other features included a hotel and an automated sorting system for mail and baggage.

​SLIPPING TIMELINE: A BLESSING IN DISGUISE

Initially the completion date for the new midfield expansion was 1972. However, the timetable slipped by years due to airline politics, economic downturns, financing issues as well as discussions about a second airport. This had a major advantage: there was ample time to adjust and fine-tune the design for the midfield complex.

By 1971 the original design was still more or less intact. However, the central area had been reduced from 600 to 200 feet and the people mover was no longer elevated.

The layout was very much tailored to Atlanta's "O&D" (origin and destination) passengers. However, at the time 70% of passengers changed flights at the airport. With the proposed design, most transfer passengers would have to change terminals in order to catch their onward flight.

Even cities that had large volumes of connecting passengers had never specifically addressed this situation: they had merely adapted standard airport designs. Therefore, no precedent existed from which Atlanta's planners could draw.

A BREAKTHROUGH

In a conceptual breakthrough in 1973, the complex had been split into two distinct sections, airside terminals with aircraft parking gates and landside terminals for ticketing and baggage.

Roadways and parking were moved away from the aircraft gates and concentrated around the landside facilities, making the roadway system much simpler, while still creating curb space for hundreds of cars per hour.

Although the separation was not considered particularly significant at the time, it marked the point at which the airport veered away from its "drive to the plane" stance and began to deal with the particular requirements of a transfer airport.

Originating and terminating passengers would shuttle between the terminals and six airside concourses on a sunken but exposed people mover system, the sole means of transportation within the complex.

As ticketing and baggage facilities no longer had to be provided in each airside terminal, more aircraft gates could be added. The elimination of roadways and parking freed additional space.

LAST BUT NOT LEAST

Another major change was to come in the winter of 1975. Due to an ice storm at Dallas/Fort Worth International Airport, the Airtrans people mover system, the ground level people mover that had been a model for Atlanta's planning, became paralyzed.

The designers realized that Atlanta's system would be vulnerable under similar conditions. It was a risk that airlines would not accept. Thus, during an intense brainstorming session Delta's facility department recommended covering the "ditch" that contained the people mover system, thereby protecting it from the elements.

Putting the people mover underground also removed the barrier between the north and south runway systems and eliminated the need for costly taxiway bridges. Also, the taxiways that in earlier layouts had separated the landside and airside terminals could be eliminated.

Next the Delta team recommended that two parallel terminals replace the three landside linear landside buildings. This move, coupled with the removal of the taxiways, allowed the half-concourse to become a full concourse, adding twelve gates.

THE FINAL STEP IN CREATING THE "ATL" WE KNOW TODAY

A final critical step was to divide the people mover tunnel into two chambers and separate them to allow for a pedestrian mall in between. Lastly, the planners re-positioned the terminals from a north-south to an east-west alignment and placed them back to back.

The number of concourses was reduced to four domestic concourses boasting 26 gates each, with space to build a fifth concourse.  An international concourse was added adjacent to the north terminal. ​

On April 18th, 1977, the contracts for construction of the terminal building and the people mover were awarded and construction could begin, almost ten years after the start of the design process. All good things take time!

For this blog the fantastic 1989 book "A Dream Takes Flight" by Betsy Braden & Paul Hagan was a huge inspiration. I highly recommend this book to anyone who wants to know more about the history of Atlanta Airport pre-1990.

​Back in the late 1990s, Frankfurt Airport considered re-configuring its runway system to an Atlanta-style layout with four parallel runways. Read the story behind this plan below!

BACK IN TIME: THE NEED FOR A NEW RUNWAY

The idea of building an additional fourth runway for Frankfurt Airport was first proposed in 1997 by Lufthansa's then-CEO Jürgen Weber. The year prior, Frankfurt had handled over 38 million passengers and 386,000 aircraft movements. The runway layout allowed for 80 movements per hour, translating into about 420,000 annual movements. Thus, the capacity ceiling was in sight.

With nearby competitors Amsterdam Schiphol and Paris de Gaulle adding new runways and planning to increase their hourly capacity to a 120 aircraft movements, something needed to be done.

A proposed new runway would allow the number of hourly takeoffs and landings to grow by 50% to 120 per hour, translating into over 660,000 annual movements and doubling the number of annual passengers to over 72 million by 2015.

Frankfurt's last new runway, the north-south runway named "Startbahn West" (West Runway) had opened in 1984 and became the focus of intense protests by environmentalists, which even lasted three years after the runway had opened.

​COMMUNITY INVOLVEMENT

​With this experience still in mind, the airport decided to closely involve residents of the surrounding communities in the planning process. A pact was made stipulating that the new runway could only be built if it was supported by the majority of nearby residents.

Fourteen different variations for increasing runway capacity were studied. The main options involved building a new runway northwest, northeast or south of the airport. Other options were to optimize the current runway system by using new procedures and technologies or by realigning the runway system.

​Yet another option saw part of traffic being transferred to nearby Erbenheim Airport, a general aviation airport located 9 miles (15 km) west of Frankfurt Airport. The remaining options were different combinations of the above options.
​
THE ATLANTA MODEL
​
The most ambitious option involved building two new east-west oriented runways south of the existing airport, providing the airport with four parallel runways and allowing both simultaneous parallel takeoffs and landings. Under this option, the north-south runway would be closed. The layout was appropriately named the "Atlanta Model". 

Depending on the mix of aircraft, this layout would allow up to a 150 aircraft movements an hour, as opposed to 120 with most other expansion options. Unsurprisingly, this was the option backed by the home carrier Lufthansa, which operates a global hub out of Frankfurt.

Although never explicitly stated at the time, the Atlanta Model would also have the additional benefit of enabling the airport to do a bit of "land grab", by creating a huge new midfield area, similar to what Schiphol did with the addition of the infamous Polderbaan.

​The midfield area--nowadays largely developed with cargo and maintenance facilities--could eventually have been used to develop a large new passenger terminal complex for Lufthansa and its partner carriers.

POLITICAL REALITY

The Atlanta Model was not without its issues. Until the majority of traffic would move to a future midfield terminal,  taxiing times to/from the existing terminals would be long and aircraft would have to cross the existing parallel runways, raising the risk of runway incursions. Also, part of the then new Cargo-Sud (Cargo-South) complex would have to be torn down.

From a community point of view, the problem with the the Atlanta Model was that it would almost double the airport in size and 600 hectares (1500 acres) of city forest would need be to cut. Also, the number of people affected by aircraft noise would increase by almost half a million. This made the Atlanta Model politically unattainable, and thus, it disappeared off the table.

A COMPROMISE

Three options remained: the construction of a single new runway north-east, north-west or south of the airport. ​The conclusion was that a runway north-west of the airport site would have the least impact on local residents and the surrounding environment.

​The runway's location--north-east of the existing airport and squeezed against the autobahn A3--was quite ingenious in that the layout is extremely compact, thereby barely increasing the airport's footprint. Only a relatively small amount of trees would need to be cut down to build the runway. Also, the amount of additional people affected by noise would be limited to about 225,000.

LANDINGS ONLY

As part of the concessions to get the buy-in from local communities, the runway would be used exclusively for landings, and only aircraft types up to the size of an Airbus A340 would be allowed to use the runway. 

In December 2007, the plans were approved by the Hessian government (Hesse is the state where Frankfurt is situated) and construction on the runway started in early 2009. In October 2012, after 15 years of discussion, planning and construction, Frankfurt opened the fourth runway, providing the airport with a total of three east-west parallel runways and one north-south runway.

The things that could have been if they had gone with the "Atlanta Model"! What do you think? Let us know your thoughts in the comments below!

Fans of the classic disaster movie "Airport" (1970) know that the movie was shot at Minneapolis-Saint Paul International Airport. But did you know the Master Plan for the expansion of "Lincoln International Airport", a fictional Chicago airport, was based on that of Houston Intercontinental Airport? Read all about it below!

THE MEADOWOOD CONTROVERSY

Frequent readers of this site know I am a huge fan of the classic airplane disaster movie "Airport". The name of this blog honors this great movie.

One of my favorite scenes in the film is when the airport manager, Mel Bakersfeld, argues with Commissioner Ackerman over closing down the airport to reduce noise over "Meadowood". Meadowood is a wealthy suburb which is suffering under the noise produced by aircraft using the airport's only available runway that night, Runway 22.

In the scene, Bakersfeld, played by the legendary Burt Lancaster, makes the case for a modern and expanded airport, where Meadowood would be re-zoned for industrial use. Here's the scene, with credit to Universal Pictures. Question to self: why do I suddenly feel like a smoke?

AN ALTERNATE TAKE ON THE HOUSTON AIRPORT MASTER PLAN?

As a kid back in the early 1980s, I used to pause the VHS tape at this very scene and copy the Master Plan layout on drawing paper. ​Later on, as I became familiar with airport layouts around around the world, I realized that the runway layout was very similar to that of Houston Intercontinental Airport.

​Houston opened in 1969, the year "Airport" was filmed. Have a look at the screenshot below, specifically the layout map mounted on the wall. 

​Now, compare that to Houston's 1971 Master Plan in the image below. Full disclosure: I did a bit of improvising here. In the 1971 Master Plan of IAH, the left cross runway (15R/33L) is actually indicated as a taxiway.​

THE TERMINAL

​For the passenger terminal, the Lincoln plan depicted an octagon-shaped building consisting of passenger terminals and multi-level parking structures. The airport administration building and tower were located at the heart of the complex. 

The fictitious ​terminal boasted two large piers on opposite sides of the main building, with mini piers or fingers protruding out from the main concourse. The plan also featured four circular satellite buildings.

​Although the plan had "Hollywood sexy" written all over it, I remember thinking even back then how challenging it would be to process all the vehicular traffic. Also, the complex had zero possibilities to expand or to be adjusted. Having said that, it certainly wasn't the worst airport plan produced in the 1960s!​

Like the Lincoln scheme, Houston Intercontinental's real terminal complex was and is aligned in an east-west direction, but that's where the comparison stops. The real Houston had two terminal buildings, with each building having four satellite concourses attached to it, and with room for two more terminals in the Master Plan (see below). And similar to other major airports of the era, Houston featured a spine road connecting the terminals.

​However, the original 1962 Houston Master Plan did have a centralized terminal which strongly resembles that of Lincoln. Take a look below!

It's very likely that there have been several iterations of the Houston Intercontinental Airport Master Plan between the 1962 version and the final version, including a version which might be much closer to the plan depicted in the movie.

​Together with the crew of Houston's 1940 Air Terminal Museum, we're trying to get to the heart of the matter! We'll keep you posted on our progress.

Did we convince you? Did you see any other similarities that we didn't discuss? Let us know your thoughts in the comments below! If you haven't seen "Airport", please go buy the DVD here. 

I want to extend a special thank you to Geoff Scripture and Michael Bludworth of the 1940 Air Terminal Museum in Houston for their help in preparing this article. As soon as the world returns to normal, go visit this great museum!

THE EVOLUTION OF BWI THROUGH AERIAL IMAGES

This year, Baltimore/Washington Thurgood Marshall International Airport is celebrating its 70th anniversary. On June 24th, 1950, President Harry S. Truman dedicated "Friendship International Airport". 

In this post, we feature a series of aerial images showcasing the spectacular growth of the passenger terminal at "BWI" through the decades.

An aerial view of Friendship Airport around the time of opening in 1950. Scheduled airline service began one month after opening. At the time, the airport was viewed as the most advanced in the United States.

An aerial view taken in the late 1960s. By this time, the original terminal had been expanded in both directions and two new concourses had been added. The pier to the left of the image--Pier C--was operated by United; Pier B in the middle by Eastern, Piedmont and Allegheny Airlines; and Pier A to the right by all other airlines.

A 1985 aerial. By this time the terminal radically altered its appearance. In the late 1970s a major renovation of the terminal complex was completed. The project doubled the size of the terminal to 635,000 square feet (59,000 square meters), The number of gate positions increased from 20 to 27. By 1983, ​Pier D (right of image) had been expanded from seven to 19 gates to meet Piedmont's hub operation needs.

A 1991 aerial view. A new, four-level parking garage, located in the front of the main terminal is being completed. A few years prior, the terminal had been expanded with a new commuter terminal and expansion of Pier D to handle the growth of the USAir/Piedmont hub operation.

In 1997, the Governor William Donald Schaefer International Terminal (foreground) opens. The $140 million project features light rail service on the lower level. Total passenger traffic at BWI reaches more than 14 million, a new record for the fourth consecutive year.

In 2005, the new Terminal A/B facility was officially dedicated at BWI Marshall Airport. The 510,000-square-foot facility provides 11 new gates for Southwest Airlines, which connect to 15 current gates on Concourse B, creating a compact, 26-gate concourse facility.

We close with this 2016 aerial. Since then the airport has expanded even further. We are currently working on a full feature on the history of BWI, which will include the latest extensions. Make sure you sign up for our newsletter below to know when it goes online!​

,Following the recent 62nd anniversary of the modernized and expanded London Gatwick Airport, we went digging in our extensive AirportHistory archives. From this, we found a batch of very rare color images of the airport taken shortly after opening of the newly-built terminal. Have a good look and enjoy!

A (VERY) SHORT HISTORY 

Initially known as the Surrey Aero Club, Gatwick had existed since 1930. Four years later, Gatwick, located 30 miles (48 kilometers) south of Central London, became the reliever airport for Croydon Airport, then the main airport for London.

Two years later, in 1936, the trendsetting "Beehive" terminal was dedicated. Among others, the Beehive featured predecessors of the modern boarding bridge.

In July 1952, it was decided to modernize and expand Gatwick. The airport was to serve as a reliever airport for Heathrow--then still called London Airport--focusing on flights to the Channel Islands and Mediterranean holiday destinations. 

The Stage 1 scheme involved the erection of a box-like terminal building and pier, the construction of a new railway station to serve the airport, and a 7,000-foot (2,134-meter) single runway with associated high-speed taxiways, parking areas and aprons.

On June 9th, 1958, the expanded London Gatwick Airport was dedicated by the Queen. Having cost GBP 7.8 million, Gatwick became the first airport in the world with an integrated railway station.

​Now, without further ado, let's have a look at the images!

We hope you enjoyed these photos. Do you remember visiting 1950s and 1960s Gatwick? Leave a comment below!

In the future, we'll be posting a full history on Gatwick Airport as well as more themed photo specials.
