What happened
On the evening of the accident, an Eastern Air Lines flight, operating a Douglas DC-7B, departed from New York-JFK on a scheduled route toward Richmond. During the initial climb phase, the crew was executing a series of heading changes as part of their departure procedure. While climbing through approximately 3,700 feet, Departure Control notified the crew of nearby traffic, identified as Pan American flight 212, positioned to their northeast.
As the Douglas DC-7B transitioned from a heading of 090 degrees to 170 degrees, it was in a 35-degree bank. At this time, the Pan Am Boeing 707 was flying approximately 700 feet lower and four miles away. Due to the aircraft's orientation and the lack of visible horizon against the dark background of the ocean, the crew's ability to judge the altitude of the approaching traffic was compromised.
Upon completing the turn, the two aircraft were on a converging, nearly head-on course. As the Pan Am aircraft initiated a left turn toward a heading of 360 degrees, it created the visual illusion of an imminent collision. In response, the pilot of the Eastern flight performed rapid evasive maneuvers, including a roll and a pull-up. These actions resulted in the Douglas DC-7B entering an unusual attitude from which the crew could not recover, leading the aircraft to strike the sea and disintegrate.
Findings
- The primary factor was the evasive maneuvers performed by the Eastern Air Lines crew to avoid a perceived collision.
- Visual illusions caused by the converging flight paths and the lack of a visible horizon contributed to the pilot's decision-making.
- The rapid maneuvering placed the aircraft in a state of spatial disorientation, preventing recovery from the vertical bank.
