Should we also be concerned that both pilots had to remove their helmets, presumably because the standard helmet connection to the aircraft was difficult/impossible to disconnect under the pressure of the situation? Any sensible aircraft/avionics designer should know (in the 21st Century) that a straight pull plug is essential for rapid egress in an emergency.
That sort of error was expected to be sorted in the 1930s, and could well have heavily contributed to the death of the pilot who had tried to escape unsuccessfully.
Furthermore, why on earth did such an operation not provide UEBS as a mandatory standard for the crew?
