Detail of the "leg" of the hatch, part of the hatch actuator assembly. When
installed on the spacecraft, an actuator rod would be connected via a pin to
the base of the "leg", allowing it to pivot (e.g., see the pilot's hatch on Gemini 8 at Neil Armstrong Air & Space).
Unlike the Mercury and Apollo spacecraft, the Gemini spacecraft did not use a
launch escape tower; rather, it was equipped with jet fighter-style ejection
seats. In an emergency, a pyrotechnic system would push a rod upward to open
the hatches, making way for the ejection seat.
