I lost the best friend I ever had as a boy to a low altitude ejection from an F86A. In those days at low altitude with a high rate of sink you didn't have a chance. His chute never opened and he died in the seat on impact.
Today's seats are marvels of high tech engineering. Flying high performance jets would be impossible without the work done by the people involved in this industry.
Just my way of saying "Thank you".
