I just fell down today, in fact. I was going up a hill, shifted to the small sprocket, chain shifted too far, and off the chain ring. I managed to shift it back on, but then it locked up. I had the cadence sensor magnet mounted on the spoke of the small chainring, because my cranks are too far from the chain stay to put it there. Not sure exactly what happened, but either:
(a) the magnet (which was held on with a zip tie) by came lose and got tangled between the chain and the sprocket, causing the chain to derail. When I shifted the chain back on, the magnet and zip tie got tangled in the works, causing things to lock
(b) the chain derailed, knocking the magnet loose. When I shifted it back onto the sprocket, the magnet and zip tie got tangled in the works, causing things to lock
When it locked up, and the bike coasted to a stop, I kind of track-stood for a second. I didn't unclip (refexively tried to pull up, rather than twisting--my panic reflex from 30 years of riding with clips & straps). I was thinking about whether I wanted to fall into the road, or into the ditch. I chose the road. Didn't put my arm out to break the fall, since I've learned that that's a mistake.
Results: not disasterous. Fell on my side. Didn't fall under a car. scraped a knee and an elbow. Ruined the magnet. No damage to the drivetrain.
