Terminal 5 was an art exhibition that took place in October 2004 at the then disused Eero Saarinen–designed TWA Flight Center at JFK Airport in Queens, New York.[1][2] The City of New York had designated both the interiors and the exteriors of the Saarinen terminal a historic landmark in 1994[3] (the building ultimately to be listed on the National Register of Historic Places),[4] but following TWA's continued financial deterioration during the 1990s and eventual purchase by American Airlines, the Saarinen-designed terminal had ended operations in October 2001[5] and entered a period of disuse.
Originally planned to run from October 1, 2004 to January 31, 2005,[8] it closed abruptly after the opening event when a runway-side door was opened by a guest, thereby breaching airport security and creating a public risk.[2][10][11] Since the exhibition, portions of the original complex have been demolished, and the Saarinen terminal (or head house) has been renovated, partially encircled by and serving as a ceremonial entrance[12] to a new adjacent terminal completed in 2008. Together, the old and new buildings comprise JetBlue Airways' JFK operations and are known collectively as Terminal 5 or simply T5 — from which the exhibit derived its name.[citation needed]
