Pilot Officer Smith, from USS Wasp, 9 May 1942, during a replenishment mission of Spitfires to Malta. His external fuel tank feed system failed so he landed back aboard after all the other aircraft had gotten airborne. Ref The Spitfire Story by Alfred Price Revised Second Edition page 132. This doesn't actually say he was RCAF, just Canadian.
Tah-dah ... ! We have a winner. Jerrold Smith it was. Spits were just too damn valuable to ditch one in the drink unintentionally. Must have been quit a dicey thing. I wonder if it was ever photographed.
