Ernst Udet
In June 1936, Ernst Udet took the He 118 on a test flight but after commencing his first dive from about 13,000 feet the propeller suddenly feathered, shearing the reduction gears, and the He 118 disintegrated, leaving Udet to parachute to safety. The Ju 87 repeatedly demonstrated dives at 90 degrees with no trouble, and so won the contract.
