Operation Aphrodite was a top-secret attempt by the Army and Navy to turn old airplanes into suicide drones during World War II. B-17s and B-24s that were past their service life would be packed with several tons of Torpex, an explosive with twice the power of TNT, and then piloted into heavily-fortified targets.
The planes would take off under control of a pilot and flight engineers before they bailed out. The drones would then be remotely piloted to targets in Nazi Germany via a "mother-plane," a specially outfitted bomber with remote control of the drone. The hope was that the concentrated mass of explosives would be successful in cracking bunkers and other defenses that survived standard bombing runs.
One of the pilots killed in the operation was the older brother of future-President John F. Kennedy.
Navy Lt. Joseph P. Kennedy had completed his quota of missions months before, but he and his crew had stayed in theater to support the D-Day invasions and the beginning of the advance across Europe. They served primarily in anti-submarine patrols. By the end of July 1944, Kennedy's crew was headed stateside.
Kennedy again volunteered to stay and joined Operation Aphrodite where he was assigned to fly drones to 10,000 feet before bailing and allowing the mother-plane to take over.
Kennedy and Lt. Wilford J. Willy flew a BQ-8, the designation for the converted B-24s, on August 12, 1944. Kennedy and Willy never made it to their bailout point. The cause of the mishap was never discovered, but the explosives on the Liberator detonated prematurely, killing both pilots and destroying the plane instantly.
Kennedy was posthumously awarded the Navy Cross and the Air Medal.
The failed missions of Operation Aphrodite would continue until the following January when the program was indefinitely suspended and never restarted.
