What is Ejection Seat?
In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft (usually military) in an emergency.
Furthermore, In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it.
The concept of an ejectable escape crew capsule has also been tried. In addition Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft
Supersonic travel is the rate of travel of an object that exceeds the speed of sound (Mach 1). Most noteworthy For objects traveling in the dry air of a temperature of 20 °C (68 °F) at sea level. In addition, This speed is approximately 343 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h.
