Today’s invention is a modification to the idea of ejector seats.
The cockpit of an aircraft would run down the spine of the fuselage.
When about to eject, this would stand on end as shown, forming a streamlined, blade-like tube containing the separate, pressurised capsules of each crew member.
The tube would be long enough to reach the free stream around a supersonic aircraft, so that ejecting crew members could leave the plane at a much lower speed and suffer far lower acelerations in doing so.
