I had read 430 mph - so fast that the aircraft was virtually pulverized upon impact.
Plausible to open doors & jump out?
No.
“Plausible to open doors & jump out? No.”
Of course not. That’s why everyone has to be on the wings
so they can all jump at the same time.
“What was the speed at impact? I had read 430 mph”
Doesn’t matter. Once the people jump and leave the airplane
they would no longer be traveling with it.
