What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Parachutist exited aircraft with 12 others. His parachute was observed to deploy normally. The parachutist was observed performing a maneuver that entangled him in his main parachute. He attempted to release the main, but it was tangled around his legs. When he deployed his emergency parachute, it got caught in the main and failed to deploy.
