According to the DC-8's flight data recorder, the aircraft was 12 miles (19 km) off course, and for 81 seconds it descended at 3,600 feet per minute (18 m/s) while slowing from more than 400 knots (460 mph; 740 km/h) to 301 knots (346 mph; 557 km/h) at the time of the collision.One of the DC-8's starboard engines struck the Constellation just ahead of its wings, tearing apart a portion of the fuselage. The Constellation entered a dive, with debris continuing to fall as it disintegrated during its spiral to the ground.The initial impact tore the DC-8's engine from its pylon. Having lost one engine and a large part of the right wing, the DC-8 remained airborne for another 90 seconds.The DC-8 crashed into the Park Slope section of Brooklyn at the intersection of Seventh Avenue and Sterling Place (40°40′38″N 73°58′25″W), scattering wreckage and setting fire to ten brownstone apartment buildings, the Pillar of Fire Church, the McCaddin Funeral Home, a Chinese laundry and a delicatessen. Six people on the ground were killed.[12][1]The crash left the remains of the DC-8 pointing southeast toward a large open field at Prospect Park, blocks from its crash site. An occupant in one of the affected apartment buildings said that his family survived because they were in the only room of their apartment that was not destroyed. The crash left a trench covering most of the length of the middle of Sterling Place. Witnesses thought that a bomb had detonated or that a building's boiler had exploded.The TWA plane crashed onto the northwest corner of Miller Field at 40.57°N 74.103°W, with some sections of the aircraft landing in New York Harbor. At least one passenger fell into a tree before the wreckage hit the ground.[11][1]There was no radio contact with traffic controllers from either plane after the collision, although LaGuardia had begun tracking an incoming, fast-moving, unidentified plane from Preston toward the LaGuardia "Flatbush" outer marker.[13]
