The U.S. Navy launches the TDN-1 Drone while steaming off Traverse City, Michigan, during flight tests on August, 10, 1943. This plane has assumed an excessive nose-up attitude and is probably about to stall. The Navy used these aircraft to train and certify pilots to take off and land from aircraft carriers during World War II. As this was a training site, crashes and emergency water landings were frequent. The U.S. Coast Guard operated small yard patrol craft to rescue the pilots and drop a buoy over the downed plane to mark the location for recovery. Not all planes were recoverable, however, and more than 100 remain on the bottom of Lake Michigan.
