I think psychology had a huge part to play in the whole thing, and to be fair was some thing the programme didn’t even touch on.
The guy likes sky diving, and has done everything that you can do in the sport, so needs a challenge, the next challenge is to go higher than anyone has before. Great.
However, what he didnt realise was that he wasn’t actually going to be sky diving, a point made by the guy who had been there and done it, he was essentially a bomb/aircraft. I assume this took Felix out of his comfort zone/control zone, and quite frankly scared him, just like some one who has never done a sky dive before. It obviously took him a year to get his head around it.
IMO he sounded petrified in the jump, where as the old guy sounded in control. It wasn’t what he signed up for.
