9. The Pan Am Building featured a Sky Club — and almost included theaters

Roth’s original plan for the 50-story building called for three theaters with a total capacity of 5,000, an open-air restaurant on the seventh floor and a 2,000-spot parking garage. While these plans did not come to fruition, some of the plans were adapted into the Sky Club, a private lunch club on the 56th floor. The Sky Club featured a private restaurant for members, who included the founder of Pan Am Juan Trippe. Trippe commissioned a mural made of clipper ships for the Sky Club. On the two floors above was the Copter Club for passengers of the helicopter service, although it only remained open for three or so years.
