helicopters for two hours. As a result, many critically injured survivors were not evacuated until 23:30. Eventually, four helicopters from the New York City Police Aviation Unit evacuated 21 people from the crash site. Also, major problems occurred with communication by rescuers. Radio frequencies became overloaded, and authorities on site were unable to make command decisions in some cases. The head of surgery of the Nassau County Medical Center was present at the scene, but unable to direct patients to the best locations because many rescuers were radioing the center itself to get advice on where they should send the survivors.

At these sites, doctors tagged the critically injured patients for immediate evacuation. At least 30 bodies were gathered on the makeshift morgue at the McEnroe property by 03:00 the following morning.
