Responding to your signature (What's the worst that could happen), this one's close --
Jump #75, 4th of July, 1969, homemade smoke bracket (metal standoff, hose clamp) on boot, smoke in freefall, nice flat stable pull (pre-hand deploy), pilot chute hesitation and pilot chute snags on smoke bracket, canopy (PC) deploys horseshoed, pilot chute breaks free, goes through lines and fuses, 1/2 the suspension lines slack and waving all over the place with a wad of nylon in the middle going ~100 mph. I got to tell you it didn't look like any malfunction that had been described to me in training. So, I spent about 5-8 seconds trying to figure it out (brain lock, wasn't prepared to scrap it). When I could see pinecones, cut away and got line stretch at ~200 feet.
Got very lucky. Moral -- Bad things CAN happen, and the really bad ones are those you've never heard of.
