We are talking an inexpert witness here, may or may not have been a loop and the engine may or may not have cut out in whatever manoeuvre it was, normally it will restart instantly, the only time it is a problem is if the prop stops turning, then it takes about 1500' straight down to restart - again, normally no problem, if you have the height.
No clues that i have seen to say he crashed off a manoeuvre, did a glide from 3,000'+ or what. As said before - do not know, wait for the enquiry!
