Looking WAY back, had an air show or open house ? at New River, ether late 50s or early 60s. an "HOK" came apart in the parking area,( looking at the main hanger from the parking lot , there area was on the left. it seems that one of the counter balances went out into the parking lot,,, through someones windshield; through the front headrest, and into the backseat. Damn 🙂 the stuff that keeps popping into this old farts head even scares me. LOL LOL P.S. i think that was the same show where they had the one man choppers.
