Unfortunately, it was not possible to ascertain the reason why the crew decided to follow such wrong procedure. In conclusion, on the basic of the foregoing, the Board determined that the probable cause of this accident was the action of the pilot in maintaining the direction of takeoff toward higher terrain over which adequate clearance could not be gained.

Accident narrative
The four engine aircraft left New York-La Guardia Airport at 1214LT bound for Berlin, Germany, with intermediate stops in Gander, Shannon and London. While descending over Newfoundland, the crew encountered poor weather conditions and was forced to divert to Stephenville-Ernest Harmon Airport where he landed at 1630LT. For operation reasons, the crew should have a 12 hours rest time and the next departure was then scheduled at 0445LT the following morning. By night, the crew started the takeoff roll from runway 07 and after rotation, continued straight ahead when few minutes later, at an altitude of 1,160 feet, the aircraft hit the slope of a mountain and crashed in a dense wooded area located 7 miles northeast of the airfield. The aircraft christened 'Flagship New England' disintegrated on impact and all 39 occupants were killed. At the time of accident, weather conditions were considered as good with a ceiling at 5,000 feet (overcast) and a visibility above 10 miles. Crew: William A. Westerfield, pilot, Robert Beckman Lehr, copilot, John B. Tierney Jr., navigator, James M. Barry, radio officer, Mark Spelar, flight engineer, Herbert B. Ewing, purser, Jerome Lewis, navigator, Margaret Ann Burleigh, stewardess.
