As part of Open House New York, I found out on a fluke that the TWA Flight Center at JFK would be accessible to the public for the first time since an ill-fated art installation in 2004.
Sadly -- while this great building designed by Eero Saarinen is being restored for future enjoyment (what its purpose will be remains unclear), I. M. Pei's National Airlines Sundrome is in the throes of demolition next door.
View my photos of both here.
