Totally correct, Phil and Bunny. 20k-plus hours in airliners has left me with ZERO recent experience in aeros and I wouldn't dream of attempting even a ferry flight in a pointy thing these days. Last aeros I flew were wobbly indeed in a Yak 15 years ago….not sure I could remember how to even strap into a MB seat. And then there's my meal-tray honed physique…and I have a class 1 med.
I have participated in an accident investigation, and the info obtained from film is amazing, particularly if the characteristics of the cameras used are known. Heat signature, energy levels, control deflections etc are all possible. If there is no recorder aboard or radar ground recording, film is IT. In this case, I believe a professional company was recording the display, and their recording in HD will no doubt be available to the AIB.
Godwilling, a recovery of AH will be a blessing in many ways, also.
