If you're an aviation enthusiast, there's a lot of fun stuff to be found in Boeing's online store. But none are as unique—and some would say even historic—as this authentic de-commissioned ejector seat from an McDonnell F-4 Phantom II fighter jet, one of the U.S. military's workhorses of the Vietnam War.

Made by the British manufacturer Martin-Baker Aircraft Co. Ltd., the seat has been refurbished and professionally cleaned, but not fully restored so it looks somewhat worn and used. It comes mounted to a steel plate for display purposes, and still includes a harness, the ejection lever, and an empty oxygen tank.

Sadly, even though the Boeing Store wants $15,000 for this collectible when it's finally available, the one thing it doesn't include is the Mk.7 rocket needed to make it eject clear of a fighter plane, a long drawn out meeting, or dinner with your in-laws. [Boeing Store via Uncrate]
