Once the decision to abandon the aircraft is taken, the only action required is to fire the seat by pulling the seat-firing handle. This does not take more than a second or two, yet Air Forces the world over have lost pilots, experienced and rookie, because they waited too long to eject. The human factors …

Eject! Eject! Eject! – Current Ejection Systems
Technological advancements in the design and development of ejection systems have resulted in significant improvements in the ejection seat and life support systems. Some of the advancements in ejection seat related sub-systems are discussed here.
Eject! Eject! Eject! – Potential for Ejection Injuries
There are different phases of ejection, with potential for injury to the pilot. Sequentially, these phases are – (a) Canopy separation/ fragmentation; (b) Egress; (c) Ram Air/ Wind blast; (d) Wind drag deceleration; (e) Free fall; (f) Parachute deployment, and (g) Landing. As per the phase of ejection, a pilot can sustain various injuries with spinal injury being the commonest.
Eject! Eject! Eject! – Biodynamics of Ejection
The force moving an ejection seat must be sufficient to enable it to clear the tail of the disabled aircraft. To achieve this, the seat must accelerate from zero velocity to about 12.2 to 24.4 m/sec (40 to 80 ft/sec). This gives a rapid rate of rise of acceleration or jolt factor, which must remain …
Eject! Eject! Eject! – An Ejection Seat
An ejection seat is a rigidly constructed metallic seat, which is forcibly ejected from the aircraft cockpit by means of an explosive charge.
