They sure were.
They could have been helmeted, gloved, and wrapped in a foot of protective suiting, and they still would have either burned to a crisp as bodies, dropped like rocks, or more likely both.
No parachutes, and flying at a speed where the reentry heat melts metal? C'mon.
I understand and agree with need for the investigation and report, but to leave the implication that somehow the reason they died was their helmets didn't fit is just balderdash.
They sure were.
