The ridge southward to Swirl How is named Top of Broad Slack, Broad Slack being a ferociously steep grass slope climbing out of Greenburn between the crags. This is the site of a wartime aircrash and bears the sad remains of a Royal Canadian Air Force Handley Page Halifax bomber. The undercarriage, together with a wooden cross and memorial cairn is on the top of the ridge with the rest of the wreckage spread down Broad Slack. During a night time navigation exercise in 1944, the RCAF Halifax from RAF Topcliffe became lost in thick cloud while over the north west of England. In an attempt to wait out the blanket of grey, they circled in hope the cloud would clear, ultimately becoming hopelessly lost. To try to get a visual fix for the navigator, the pilot dropped the bomber out of the cloud base, with no knowledge of what was below him. Unfortunately, for both him, the crew and the aircraft, they were greeted by the great rising fells of Swirl How and Great Carrs. With no time to react, the aircraft hit the mountainside killing all on board. Despite the crew perishing in the impact, the bomber remained largely intact and, to prevent other aircraft from spotting it and reporting it repeatedly, the wreckage was cut into a number of smaller, moveable pieces and discarded down Broad Slack, where parts of it are still visible today. Over the years, two of the four Rolls-Royce engines were recovered from the crash site by an RAF helicopter, one of which is now on display at the Ruskin Museum in Coniston. In contrast to the craggy scarp of the east face, the western slope of the ridge descends over grass to the col of Fairfield, forming a tilted triangular plateau. Across Fairfield is the rocky top of Grey Friar.
