In my spare time, I spent a lot of time flying for parachute clubs. Most of it was on BN Islanders. I became very adept at manouevering at low speeds on finals and also on round-out at not many feet getting round soft spots on the DZ and some of the jumping beans who had not yet landed. I could do most things with an Islander as long as I had 55 knots showing.
I know nothing about the Caravan but it seems to me that his first priority was to find somewhere safe to land and he reckoned he could get back to the airfield (which he did).
He ended up on a heading that was several degrees from the main runway heading. He had already achieved the major prize in that he (and the PJI) were most likely going to survive and then he decided to use the last bit of energy to get round the corner on to the strip.
What we don't know from the video is what he was looking at on short finals. Was there a ditch in front of him or some other obstacle? Only he could tell you that. What i can tell you is that he knew his aeroplane well and he felt that, having made the airfield, he could improve the situation for the survival of the aeroplane.
Parachute flying can be a very intensive business. You get to know your aircraft very, very well and fine judgement is the order of the day.
I can remember having an interview with Britannia (Thomson) many, many years ago. One of the interviewers told me that he was worried about my long haul experience with a 5-man crew and pointed out that they frequently did 4 sector days with a 2-man crew.
I gave him my log book and showed him one of my 38 sector days with a 1-man crew!
He was amazed and I went elsewhere.
