An ejection seat is a safety device used in aircraft, particularly military jets, that allows the pilot or crew member to escape quickly in an emergency. When activated, the seat is propelled out of the aircraft, often using a rocket or explosive charge, allowing the occupant to parachute safely to the ground. Ejection seats are designed to function at various altitudes and speeds, ensuring the safety of the individual during critical situations. They are equipped with features like a harness, parachute, and sometimes even a survival kit, making them essential for the safety of pilots in high-risk environments, such as during combat or training missions.
