On July 9, 1946, a US Army Air Force B-17G Flying Fortress, in use as a military transport, hit the northern flank of the mountain. All 25 on board died instantly in a large fireball. Some of the men were Public Health employees of the US military who had worked in Europe in World War II. Sixteen were U.S. Coast Guardsmen returning from duty in Greenland. Tiny pieces of the plane are still on the mountainside, and the site is accessible on a road built over the former funicular railway to access antennae at the summit. A memorial site, dedicated 6 July 1996, is at the location and is lit at all times.
