The aircraft bore the name Over Exposed after it was flown in July 1946 by the 509th Composite Group during Operation Crossroads to photograph nuclear testing at Bikini Atoll, including the dropping of an atomic bomb by B-29 Superfortress Dave's Dream.

At about 11:00 the aircraft hit the ground at 610m above sea level, 300m north east of the summit of Higher Shelf Stones and it was engulfed in flames.

Already on a training exercise upon the Kinder Scout moors, the RAF Harpur Hill rescue team headed to Bleaklow and located the crash site at about 16:30, by which time the light was fading.

It is about a 2-mile (3.2 km) walk to the crash site from the lay-by at the summit of Snake Pass, starting along the Pennine Way footpath through Devil's Dyke.
