MetLife Building

The MetLife Building is a skyscraper located at 200 Park Avenue at East 45th Street above Grand Central Terminal in Midtown Manhattan, New York City, was built in 1958–63 as the Pan Am Building, the headquarters of Pan American World Airways. It was designed by Emery Roth & Sons, Pietro Belluschi and Walter Gropius in the International style, and is one of the fifty tallest buildings in the United States.

Helicopter Service
The building previously had helicopter service to Pan Am's terminal at John F. Kennedy International Airport, a 7-to-10-minute flight from the rooftop helipad. The New York Airways Vertol 107 flights lasted from December 21, 1965, to February 18, 1968; Sikorsky S-61 flights operated for a few months in 1977, ending after an accident atop the building killed five people.

On May 16, 1977, about one minute after a Sikorsky S-61L landed and its 20 passengers disembarked, the right front landing gear collapsed, causing the aircraft to topple onto its side with the rotors still turning. One of the five 20-foot blades broke off and flew into a crowd of passengers waiting to board. Three men, including film director Michael Findlay, were killed instantly and another man died later in a hospital. The blade sailed over the side of the building and killed a pedestrian on the corner of Madison Avenue and 43rd Street. Two other people were seriously injured.
