Abstract: An aerial marker launcher for dropping markers from an aircraft to the ground to form a readily visible indication of the path of the aircraft. The launcher includes a container mounted on the wing of an aircraft, the container configured to hold a stack of markers and having an ejection opening in one end. An ejection means is mounted at the ejection opening and is pilot controllable to eject the markers one at a time. A pusher plate at the end of the stack is operable to urge the markers toward the ejection opening. Attached to the pusher plate is a spring assembly having a resilient retractable extension member, under tension, extending therefrom and attached to the container adjacent the ejection opening for urging the pusher plate resiliently toward the ejection opening.
