The former TWA Terminal at John F. Kennedy Airport is a significant example of 20th-Century modern architecture and engineering. A masterpiece of sinuous lines actualized out of poured concrete, it was designed by the mid-century modernist Eero Saarinen. Opened in 1962 it was the final terminal built at what was then called New York International Airport, as well as one of Saarinen’s last projects. Revolutionary and influential, it was Saarinen’s intention that the terminal express the excitement of travel and “reveal the terminal as a place of movement and transition.” Fifty years after the fact it remains as exciting and forward-looking as ever. And dare I say it, soignee. When was the last time an airport – or any public building for that matter – made you feel sexy? Saarinen’s building does just that, while sweeping you up in the promise and possibility of a future that, unfortunately, never quite came to pass. After laying dormant for over a decade, it was recently announced that the terminal would be developed into a luxury hotel. Thanks to Open House New York, yesterday was one of those last-chance opportunities to experience the building in full – before getting caught up in the inevitable tide of transition.
