Eastern Air Lines Flight 537, registration N88727, was a Douglas DC-4 aircraft en route from Boston, Massachusetts, to Washington, D.C., via intermediate points on November 1, 1949. A Lockheed P-38 Lightning, registered NX-26927, was being test-flown for acceptance by the government of Bolivia by Erick Rios Bridoux of the Bolivian Air Force. The two aircraft collided in mid-air at an altitude of 300 feet about half a mile southwest of the threshold of Runway 3 (present-day Runway 4) at Washington National Airport, killing all 55 aboard the DC-4 and seriously injuring the pilot of the P-38. At the time it was the deadliest airliner incident in United States history.
