1943 – An aircraft sinks an enemy submarine with air-to-surface rockets for the first time, as a Fairey Swordfish from the British escort carrier HMS Archer strikes U-752, a German Type VIIC, in the Atlantic. It had previously been attacked by an Allied bomber earlier in the year.
1969 – A drunken U.S. Air Force assistant crew chief, Sgt. Paul Adams Meyer, suffering anxiety over marital problems, starts up a Lockheed C-130E Hercules at RAF Mildenhall in the U.K. and takes off for Langley AFB, Virginia. At least two North American F-100 Super Sabres from RAF Lakenheath, a C-130 from Mildenhall, and two RAF English Electric Lightnings are sent aloft to try to make contact with the stolen aircraft. The Hercules crashes into the English Channel less than two hours later. There is speculation whether the Hercules was shot down; some wreckage was recovered but the pilot’s body was never found.
