Oh, so many stories like that.
You never reach through a simulated prop to adjust a needle-valve (I hear that noise in my nightmares. Fingers clacking in the prop. Ugh). Two of us were starting planes on newly installed club starting benches. All of the sudden that noise and my glasses are streaked with blood! That floating, disconnected feeling as I step back and do a finger count. Mine are OK. The pilot beside me bobbled his Glo-Starter and without thinking reached under the nose to get it as it was rolling off the bench. Through the prop. 20+ stitches.
Ugh, been there, got the 21 stitches on one arm, 5 on a finger myself. RC "war wounds"... family members wonder why I still like the hobby...
I had an glow ignitor locked in on a plane.
I started the engine, and the ignitor worked loose as I ran the engine up... it dropped into the prop...
The prop hit it, and flung it right into the middle of my forehead.
After everyone at the field realized I was OK, they burst out laughing at the whole thing, especially once they saw the "third eye" bump I had...
