- Afterburner - A system in the engine(s) of many tactical aircraft which dramatically increases thrust at the cost of doubling (or more) the fuel consumption

A classic aircraft maneuver used to honor the dead or missing. The simplest type of missing man formation consists of four aircraft that begin in what's known as the "fingertip strong right" formation. That means they're in the shape of a V, with the right arm—from the pilots' perspective—longer than the left. If you think of the relative positions of your fingertips when you look at the back of your right hand; the leader (or middle finger) has two planes (the ring finger and pinkie) trailing off his right wing and one (the pointer) off his left. As the V passes overhead, the plane in the ring-finger position peels away into the sunset, sometimes trailing a cloud of smoke.
