Eugene L. Vidal, Aviation Accident Report: 1935 private Welch aircraft crash (1935)
“ According to statements of witnesses, the pilot had made about two-thirds of a turn necessary to get the plane in a direction for landing on the airport when he throttled his engine to complete his landing approach in a glide. At this time the nose of the plane was seen to drop and the plane continued into the ground from an altitude of about 250 feet in what appeared to be a spiral. The plane was equipped with dual controls which had not been removed. It is possible that the passenger interfered with the controls during the glide for a landing but it is not thought probable. ”
