If they were immersed in water they would have survived.
Submerging a human in liquid of the same density pretty much negates all G forces from acceleration and shock, filling the lungs as well improves to near perfection.
Those impossible accelerations people say UFO's do are indeed be possible with a liquid cockpit.
The craft I remember in my childhood, had no propulsion system I could understand, it seemed that the 4 main triangular Quadrant panels that made up the triangular wedge shape had a form of energy directed into them by the ring to maneuver by varying the degree to which each panel received the energy.
It feels like it was some kind of vibrational force involving resonance or at least that was the vibe I got.
To busy to draw it out and the CAD mock up is 404. Just imagine a triangular wedge with a cockpit ball in the back and a glowing ring around it.
The cockpit doubled as a inertial gyroscope, the craft would torque on the spherical cockpit to rotate itself around and aim its main gun.
Looked alot like if you smushed a Tie Interceptor, filled the cockpit with liquid and made it freely rotating then put a glowing blue ring inside it. Probably the best mental image I can give.
The triangular panels it was covered with were definitely the method it used to move around, it had no propulsion system as we think of one. The panels seemed to hum while maneuvering and flying.
