On 21st June 1944, Martin B-26B Marauder #41-18042 crashed while flying a non-operational flight in low cloud over Slieve Gallion, Co. Londonderry. The crew of 6 had taken off from U.S.A.A.F. Station 239 at Toome Airfield, Co. Antrim.
Three members of 3rd Combat Crew Replacement Center, United States Army Air Force died as a result of the incident. They were pilot Joseph B. Devilbliss, bomber navigator Frederick Christopher “Chris” Ahrens, and radio operator Alfred J. Knap. Two other Marauder aircraft on the same non-operational flight returned safely.
Authorities declared the Marauder written off, damaged beyond repair. Poor visibility in low cloud over the mountain was likely the cause of the American plane’s fate.
Second Lieutenant Frederick Christopher "Chris" Ahrens was part of the crew of a B26-B Marauder that came down on Slieve Gallion, Co. Londonderry in 1944.
Second Lieutenant Joseph Bayard Devilbliss was part of the crew of a B26-B Marauder that came down on Slieve Gallion, Co. Londonderry killing 3 crew members.
