A Douglas DC-3 passenger plane, operating Pennsylvania-Central Airlines Trip 19, was destroyed when it crashed near Lovettsville, VA, USA. All 25 occupants were killed. One of the passengers killed was Senator Ernest Lundeen (62, Minnesota). Trip 19 was a scheduled service from x to y with several intermediate stops. The airplane took off from Washington-Hoover Field, DC at 14:21. Twenty minutes after departure the airplane flew into dark storm clouds near Short Hill Mountain. A lightning discharge occurred near the airplane, after which it descended out of control. It struck the ground on the edge of an alfalfa field in a nose-down attitude. PROBABLE CAUSE: “Upon the basis of the foregoing findings of probable fact and the entire record in this investigation, we find that the probable cause of the accident to aircraft NC 21789, which occurred at Lovettsville, Virginia, on August 31, 1940, was the disabling of the pilots by a severe lightning discharge in the immediate neighborhood of the plane, with resulting loes of control.”
