New York Airways rooftop collapse (1977)
For years, helicopters ferried commuters between Manhattan rooftops and area airports. In May 1977, a parked helicopter's landing gear failed atop the Pan Am Building. A rotor blade broke loose and killed five people, four on the roof and one on the street below.
New York Airways suspended rooftop service almost immediately. The route never fully recovered.
The accident helped end the idea of routine urban rooftop air commuting in New York for decades.
It shows how a single accident can freeze public trust in flying over cities. SkyDrive's 300 incident-free flights are aimed squarely at that fear.
