For those who don't know, some background information about these particular crashes, and others...
We know about American 587.
We also know about the 9/11 hijackings.
TWA 800 crashed into the Atlantic off Long Island. All aboard killed.
In '92, a USAir F-28 overran the runway at LaGuardia, crashing into Flushing Bay after being improperly de-iced. 27 of 51 on board killed.
In 1990, an Avianca 707 crashed into a wooded suburban area on Long Island while on approach to JFK. Bad weather led the aircraft to be put into a holding pattern, after which, difficulty communicating between the flight crew and ATC caused a serious underestimate of the fuel exhaustion danger the aircraft was in. While circling, the plane ran out of fuel and crashed. [As a side note, one of the passengers was found to be carrying illegal drugs in his body]
In 1989, a USAir 737-400 overran the runway at LaGuardia, crashing into the East River. The aircraft's rudder trim had been improperly set at full left, causing the aircraft to lose control. 2 out of 63 aboard killed.
An Eastern 727-200 crashed on approach to JFK in 1975 after encountering severe windshear just before reaching the runway. Microburst was so severe, pilots flying the exact same approach under same conditions in the simulator afterwards could not find a way to save the aircraft. Intense fire after impact. 115 of 124 on board killed.
Eastern DC-7 crashed on approach to JFK after taking evasive action to avoid a PA 707 that ATC had placed on a converging track. All 84 aboard killed.
In 1962, an American 707 crashed on takeoff from JFK into Jamaica Bay after a rudder servo malfunction that caused the rudder to stick in a turn after the aircraft rotated. The 707 plunged into the shallow water of the bay (approx. inches-to-feet), and broke up. All 84 aboard killed.
A United DC-8 and TWA Constellation collided over Brooklyn after the United jet oversped and entered the traffic pattern at an incredibly high rate of speed. The crippled TWA aircraft struggled and crashed into a military airfield, while the United jet crashed into an urban area in Brooklyn. The only survivor of the crash, an 8 year old unaccompanied minor, died the next day. All 84 on the United jet were killed, as were all 44 on the TWA aircraft, plus 6 on the ground.
In 1959, an American Electra crashed into the East River on approach to LaGuardia after the crew misinterpreted an altimeter reading. 64 of the 73 aboard were killed.
In 1957, a Northeast DC-6 stalled and crashed after takeoff from LaGuardia. The aircraft crashed into Riker's Island, a state prison, and caught fire. 21 of 101 aboard were killed.
