Holy smoke! What a devil of a flyer. I don't know whether I find it brave or foolhardy, but apparently the pilot knows the behaviour of his machine. Incredible performance!
I can only sympathise too well with the fact that your heart sank when you had your own experience of the same kind. Even on flights where the large passenger planes suddenly plummet downwards, you can recognise what you are describing.
A long time ago, when I was still working in the PR industry, there was a competition to win a parabolic flight (the winners had previously completed a so-called cosmonaut training programme and had flown to Russia/Baikonur). Those were the days!
“Want me to do it again?”
“No man, that’s good.” We both told him.
LoL :D - Hope your second one isn't still running around somewhere. HaHa!
