On 9 December 1943, a USAAF Boeing B-17G Flying Fortress plane (en route from Goose Bay, Labrador to Prestwick, Scotland) crashed on Truskmore just east of Benbulbin. 10 airmen were aboard, of whom three died, two at the scene and one from injuries sustained in the crash. Local residents undertook a rescue mission, taking the injured off the mountain where they were then transferred to Sligo County Hospital. Substantial wreckage of the plane stayed on the mountain for many years following the crash and today limited amounts of aircraft fragments still remain at the site.
