Sources differ on the number killed and injured; up to 75 died and 100 or more were injured. According to TIME magazine, the pilot, Flt. Lt. Cesar Abadia of the Colombian Air Force, disregarded standing orders not to fly below 500 feet and attempted to dive through a narrow gap between two grandstands. The pilot misjudged his approach and a wingtip hit the Diplomatic stand; the plane then smashed against the Presidential stand and exploded, raining flaming debris down on spectators located between the two grandstands. September The Heinkel He 100 V3, D-ISVR, with clipped racing wings and a smaller rounded canopy, moves to Warnemünde for the attempt on closed circuit speed record this month.

Since the aircraft cannot be safely landed it is decided to have Nitschke bail out and let the aircraft crash in a safe spot on the airfield. Gerhard is injured when he hits the tail on the way out, and makes no further record attempts. 21 September Following the conclusion of its test program, the Hall XPTBH-2, BuNo 9721, was used for experimental duties at the Naval Torpedo Station in Newport, Rhode Island, participating in trials of aerial torpedoes.
