The most impressive thing there isn't the flight--it's the planning and judgement. He set it up so that if his skill failed on the attempt (i.e. he got a bad exit) he had room to bail out and try again. Well done, all around.
Hell yeah! Jean-Jaques is such a beast! Crushes it in whatever he's flying (check out his Onesie Power flights, my personal favorite). Super kind and humble dude too. Looking forward to adding South Africa to the list in the near future!
