pilot Lt. Robert A. Tunnel and combat cameraman Lt. David J. McCarthy, who filmed the event from the perspex nose of the aircraft. As planned, Kennedy and Willy remained aboard as the BQ-8 completed its first remote-controlled turn at near the North Sea coast. Kennedy and Willy removed the safety pin, arming the explosive package, and Kennedy radioed the agreed code Spade Flush, his last known words. Two minutes later and well before the planned crew bailout, near RAF Manston, the Torpex explosive detonated prematurely and destroyed the Liberator, killing Kennedy and Willy instantly. Wreckage landed near the village of Blythburgh in Suffolk, England, causing widespread damage and small fires, but there were no injuries on the ground. According to one report, a total of 59 buildings were damaged in a nearby coastal town. According to USAAF records, the trailing Mosquito "was flying 300 feet above and about 300 yards to the rear of the robot. Engineer photographer on this ship was injured, and the ship was damaged slightly by the explosion." The Mosquito, which made an immediate emergency landing at RAF Halesworth, belonged to the 325th Reconnaissance Wing, a unit under the command of the son of President Franklin Roosevelt, then Colonel Elliott Roosevelt, who years later claimed to have been aboard that trailing aircraft, and his version of the event has gained wide currency. However, Air Force records cannot substantiate it. Instead, an after-action account by the 8th Combat Camera Unit (CCU) noted: The 8th CCU film of the event, as far as is known, has not been found. The 20th Fighter Group out of Kings Cliffe, Northamptonshire, was tasked with providing escort to the Aphrodite mission. Escort consisted of P-51s out of the 55th and 79th Fighter Squadrons, each squadron providing two aircraft. VIII FC, Field Order 509 stated "20 GP (P-51's, 4 A/C) will proceed to Fersfield and land coordinating with operations where to provide close escort support to one B-34 special Operation." Lieutenant John E. Klink noted in his mission summary report: "Took off to excort BXXX, 1 B24, 1 B17, 2 B34s, and 3 photo Recons (2 Mosq. -1 P38). When specially loaded B24 was at approx. 2000 ft. NE of Ipswich it exploded and crashed near small lake. No one got out of the plane. Rest of ships OK in spite of terrific concussion from explosion. All returned to base." Accident investigation Drone
