  1. Cool, I worked with Vic!

  2. Only for high speed and high altitude ejections!

  3. No

  4. The spine is segregated into three regions, and things like “the twelfth vertebrae” aren’t used. Rather it is cervical, thoracic and lumbar.

  5. Spinal fractures in modern ejection seats is less than 5%.

  6. 11:09: that’s an interesting photo. Looks like an early K-36. KKO-5 full pressure suit. Never saw the webbing between the arm restraints and the seat back before.

  7. That was a pneumatic device with like 1/3 of the acceleration of a real ejection seat.

  8. Spinal fractures in modern ejection seats is less than 5%.

  9. The F-16 has only a single engine so ejections are more likely to occur than in twin engine aircraft.

  10. Mere descent speed doesn’t create g-force.

  11. Heavy and primitive and didn’t perform well in low altitude or high sink rates due to the fact that the main parachute couldn’t be deployed for a full second after initiation.

  12. Meet your maker in a Martin-Baker. Those seats were some of the wort in the inventory during that time, mostly due to the high angle between the seat back and the acceleration vector.

  13. Most ejections occur below 300 knots.
