Folded Wings on TBM-3E Avengers at "Planes of Fame Air Show", San Bernadino County, Chino CA.
Wings on the Avenger were designed to be folded back laterally along the fuselage to alleviate the height problem upward-folding wings caused on carrier hangar decks. The hydraulically-powered wings could be folded or unfolded by the pilot in seconds with no help from ground crews.
