I seem to recall that the chopper accident on the Pan Am Building involved blades flying off and killing people both on the pad and on Vandebilt Avenue below. The aircraft itself remained on the pad.</font>
Yes - the landing gear collapsed, and when the copter fell to one side (but not off the building) a rotor snapped and went flying into a nearby office building and killed someone. This was covered on the Discovery Wings channel - apparently landing on the Pan Am building roof was always a dangerous proposition because of winds.
