May 16, 1977 –
Five people were killed on this date, when a New York Airways helicopter, idling atop the Pan Am Building in midtown Manhattan, toppled over, sending a huge rotor blade flying.
Three men 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.
