data. Following the completion of the US Army testing in 1969, it was sent to storage awaiting further tests. The Marvel was brought out of storage as a proof-of-concept demonstrator of a STOL utility aircraft for Saudi Arabia. It was fitted with a more powerful (420 hp (313 kW)) engine and longer span (36 ft 10½ in (11.24 m) wings, first flying in this form as the Marvel II on August 17, 1982. After initial tests in the United States, the Marvel II was shipped to Ta’if, Saudi Arabia, carrying out a short test program which showed that its landing gear was unsuitable for operating from soft sand and it was still underpowered, after which it returned to Mississippi. In 2000, the aircraft was displayed at EAA Airventure promoting the Mississippi State Department of Aerospace Engineering. In 2004, the XV-11A was donated to the Southern Museum of Flight at the Birmingham International Airport in Alabama.
