On the 17th August 1943, the 418th Bombardment Squadron was the lead for the 100th Bombardment Group (BG) on a mission to bomb the Messerschmitt factory at Regensburg, Germany.

From the aircraft’s MACR the intended destination was North Africa. This mission, for at least the 100th BG, was what was termed a ‘shuttle run’.

The return missions for the 100th BG was on the 24th and 25th August 1943 when they bombed targets in France before returning to Thorpe Abbot.

The aircraft was last seen to turn back from the formation near Frankfurt at 10:20 hrs but still under control. Ten parachutes were reported to have been seen leave the aircraft.

The aircraft exploded in midair with the wreckage falling to earth at 11:40 hrs about 500 m (1600 ft) west of Schmalgraf, near Kelmis in Belgium.

S/Sgt. Barney was blown out of the aircraft when it exploded. He believed that the six crew who perished did not bail out.

Original narrative which is being researched

Shot down by enemy fighters (Hauptmann Von Bonin,Oberleutnant Barte and Leutnant Witzke), the aircraft crashed at Herbesthal Lontzen, 500 meters west of Schmalgraf, near Kelmis, west of Aachen, Belgium.

Much has been written about the 'Legend' of the 100th Bomb Group being 'picked on' or singled out by the Luftwaffe for punishment because a 100th Group B 17 had, during the Regensburg raid, pulled out of formation with battle damage and then lowered its wheels in a supposed token of surrender. Then, when approached by several Luftwaffe fighter aircraft, its gunners were supposed to have opened fire and shot down several of the German planes.

The six who perished were initially interred at the Cemetery of Honor, Eupen in Section 16, Grave numbers 218 to 222 and 232.
