The crew departed RAF St Eval on a positioning flight to Thurleigh, the crew returning to base. Approaching the destination, weather conditions worsened and the pilot was forced to return to St Eval. On approach, the pilot overshot and initiated a go around procedure then the airplane was never seen again. As it failed to return, SAR operations were conducted but no trace of the airplane nor the crew was ever found. During these SAR operations, two RAF planes were lost as well. It is believed that the B-17 crashed somewhere in the Celtic Sea off RAF St Eval. Lost without trace.

The airplane departed RAF St Eval on an anti-submarine patrol mission with a crew of six on board. While returning to base at the end of the afternoon, the crew encountered foggy conditions and was unable to locate the airbase. The pilot was advised to try RAF Chivenor or Exeter but these airfields were also fogbound. Because the airplane was low on fuel, the captain ordered his crew to bail out and later attempted to land at RAF Davidstow Moor. On approach, both engines failed due to a fuel exhaustion, and the airplane stalled and crashed in Lewannick, some 13 km southeast of the airfield. The pilot was killed. All five other crew members parachuted to safety.
