Abstract: Ejection seat propulsion mechanism has a firing pin normally held cocked by a latching member that has one lost motion connection with an ''''eject'''' handle element, another with an element actuated by jettisoning of a canopy over the seat. Motion of either element alone does not move the latching member but renders the connection operative for firing pin release by subsequent or simultaneous motion of the other element. Canopy jettisoning can be effected by the handle, which actuates a switch, or by a separate canopy jettison knob. Actuation of an auxiliary handle, moved from an inaccessible to an accessible position by actuation of the ''''eject'''' handle, gives a second motion to the handle element for ejection through the canopy.
