I seem to remember an accident report looking at an AS350 (from memory) dynamic rollover outside a hangar at Fairoaks. One segment of TRB went through the hangar door (again from memory) and embedded itself in a toolbox or similar well inside the hangar.
Anyone else remember the same, and a reg so I can find the accident report? Really to see how far that blade went, and the amount of energy a segment of blade contains...
