The engine was NOT running backwards, and, interestingly, the cone remained screwed together! The prop flung out through one of the side holes in the cone. The cone hit me in the leg and fell to the ground.

The prop must have worked its way off of the end of the shaft, and within milliseconds, spun out of control, flinging off at around the 3 to 2 o'clock position, just missing the bench. It may have actually struck the bench since I heard some banging. We'll never know. I checked the bench and found no obvious marks, and the prop looked pretty much unharmed.javascript:void(opener.AddText('[sm\=71_71.gif]',''));self.focus();

Very, very dangerous, to be sure.

Like my friend said, if that prop would have pierced my heart, just as I was about to pass out, my final thoughts on this planet would be "I was just killed by my toy plane."
