Ross Vail was landing near the Folsom Pro Rodeo in California when his flag snagged on a tree, sending him flying into a tent and narrowly missing grandstands and a crowd that audibly gasped as when he was sent flying to the ground. A spokesperson for Choose Folsom, which organizes the annual event, told The Sacramento Bee: “Yesterday’s landing was certainly not the landing he intended, but thankfully, the skydiver is doing well.” The skydiver cut his lip but was able to resume parachuting the following day. No other injuries were reported.

He might be fine for all we know. There's no gore, no real evidence of any serious injury except what's in your mind. Certainly no indication he was "maimed."
