Robb Heady skydived down to 1,000 feet above the ground before deploying his parachute in order to minimize detection. He too, used a reserve chute and landed very hard, injuring himself, which forced him to spend the night in the woods before hobbling over to his car. As we know the Politizia were awaiting...
As for Richard LaPoint, I don't know when he deployed his chute. And Freddy? Flyjack would know more about his jump, I think, than me.
But those are the five copycats that jumped: Heady, McCoy, McNally, LaPoint, and Hahneman.
