Test crash data on cars is always speculative. They crash them in 'typical' ways and draw overall conclusions. But, every day, people crash cars in new and inventive ways.
I have heard Police and medics be astounded such as: "No idea how he survived that crash, everything's a total write off." and "I can't see how she died, minimal impact and everyone else walked out of it."
With aircraft, you magnify that more times than can be quantified. Surviving an impact is largely down to luck if the a/c:
- nose first
- tail first
- flat down with almost no forward speed
- fuel situation
- fire on board before impact?
- smooth surface
- rocky surface
- fuselage stay intact
- etcetera
This film was just a way to make money and all credit to them for that but not for anything else.
