The only spacecraft ever flown with installed ejection seats were Vostok, Gemini, and the Space Shuttle. [22] Early flights of the Space Shuttle, which used Columbia, were with a crew of two, both provided with ejector seats (STS-1 to STS-4), but the seats were disabled and then removed as the crew size was increased.

Sir James Martin (11 September 1893 – 5 January 1981) was a British engineer who together with Captain Valentine Baker founded the Martin-Baker aircraft company which is now a leading producer of aircraft ejection seats.
The company concluded that an explosive-powered ejection seat was the best solution. In particular, Baker's death in 1942 during a test flight of the MB 3 affected Martin so much that pilot safety became his primary focus and led to the later reorganisation of the company to focus primarily on ejection seats.

Bohlin worked on the seat belt for about a year, using skills in developing ejection seats for SAAB; he concentrated on keeping the driver safe in a car accident. After testing the three-point safety belt, he introduced his invention to the Volvo company in 1959 and received his first patent (number 3,043,625). [ 1 ]
The Martin-Baker Mk.1 is a British ejection seat designed and built by Martin-Baker. Developed in the late 1940s it was the first in the line of production Martin-Baker seats for military aircraft. Ground and air testing of earlier designs resulted in the first successful test ejection of a company employee in July 1946.
The Mk.4 seat was designed as an improved, lightweight version of earlier Martin-Baker seats for installation in a range of lighter, smaller aircraft types. [2] Improvements included a single combined seat and parachute quick release fastener (QRF) and a snubber mechanism to allow crews to lean forward without loosening the harness. [ 2 ]
Martin-Baker seats have been fitted into over 200 fixed-wing and rotary types with the most recent being the Lockheed Martin F-35 Lightning II programme. Martin-Baker claimed in 2022 that since the first live ejection test in 1945, [3] a total of 7,674 lives have been saved by the company's ejection seats. [4]
