Category: Accident
On October 26, 1944, a Douglas DC-4 aircraft, Eastern Air Lines flight 537, crashed near Washington-National Airport, DC, following a mid-air collision with a P-38 Lightning fighter. The P-38, piloted by a Bolivian Air Force officer, was performing an acceptance test flight. The pilot, responding to engine trouble, initiated a circled flight and subsequently landed near the designated runway. When approaching the runway, the tower requested the pilot’s landing instructions. The pilot responded that he had engine trouble and was in a hurry, and the tower responded that the P-38 was cleared to land number two on runway 3. The tower then instructed the P-38 to enter the left traffic pattern and land behind the C-54. A subsequent collision occurred, resulting in the destruction of both aircraft. The pilot of the P-38 survived with serious injuries.On October 26, 1944, a Douglas DC-4 aircraft, Eastern Air Lines flight 537, crashed near Washington-National Airport, DC, following a mid-air collision with a P-38 Lightning fighter.

Description

Eastern flight 537, a Douglas DC-4, crashed near Washington-National Airport, DC, USA, following a mid-air collision with a P-38 Lightning fighter, killing all 55 occupants. At 11:37 A Bolivian Air Force Lockheed P-38 Lightning fighter (NX26927) took off from runway 03 at Washington-National Airport, DC (DCA). The pilot was carrying out an acceptance test flight. Because of erratic operation of the right hand engine, the pilot decided to land as soon as possible. When abeam runway 36 the pilot transmitted, “Washington Tower, this is Bolivian P-38. I got engine trouble request landing instructions.” Waiting for instructions he circled the field. When he was between Bolling Field and the National Airport and at about 3,500 feet altitude, the tower asked, “Bolivian P-38, you were asking landing instructions?” The Bolivian pilot answered, “Yes, I have engine trouble. I am in a hurry,” and that the tower at that time responded, “Bolivian P-38 cleared to land number two on runway 3.” Number one on the approach was Eastern Air Lines flight 537, a Douglas C-54. Because the P-38 was descending above and behind the C-54, it was then told to enter the left traffic pattern and to land behind the C-54. This message was never confirmed, nor complied with. The tower then switched to the Eastern aircraft and told it to turn left. When turning left, half a mile short of the runway at an altitude of 300 feet, both aircraft collided and crashed. The pilot of the P-38 survived with serious injuries. PROBABLE CAUSE: “The execution of a straight-in final approach by the P-38 pilot without obtaining proper clearance to land and without exercising necessary vigilance.”
