The crew had left Gander in Newfoundland for Prestwick at 19:46 GMT on the 19th August, having been one of at least 23 aircraft to depart Canada bound for the UK. At 06:27 GMT the radio operator made contact with Prestwick who provided the crew with a QDM (a magnetic course to steer towards Prestwick) of 092° this placed the aircraft slight north of due magnetic west from the airfield. Contact was made again a few minutes later when the crew reported being 10 miles from Prestwick at 4500ft, the flying control at Prestwick, named Dogwatch, radioed to tell the pilots to hold their altitude until advised. No further contact radio was received from the aircraft and it was reported missing after the other aircraft in the flight that took off around it had arrived. The wreckage was located on the 23rd August by a shepherd on the western side of Beinn Nuis not far from the summit of the mountain. A watch recovered from the wreck showed the time of the crash to be 08:10. The aircraft that had taken off from Gander at around the same time were reported to have landed around 08:00. It would appear that the pilots were descending through the low cloud that covered the area that morning when they flew into the mountains of Arran.

The airplane departed Dow AFB on a transatlantic flight to Prestwick with an intermediate stop in Gander. Approaching Prestwick, the crew was in contact with ground and reported he was approaching the airfield when the airplane disappeared without distress call. SAR operations were conducted but eventually suspended four days later as no trace of the airplane nor the crew was found. Lost without trace. It is believed that the airplane may have crashed somewhere into the Firth of Clyde.
