The Prue IIA is an United States , high-wing, two-seat, T-tailed glider that was designed by Irving Prue and constructed by Ed Minghelle of Palmdale, California.[1][2][3]
Design and development
Based on the Prue Two, the IIA incorporates many changes to the basic design, including a T-tail in place of a low-tail, fixed instead of retractable landing gear, a shorter two-piece wing instead of a three-piece wing and an empty weight that is 210 lb (95 kg) lighter. The Prue IIA was built by Minghelle between 1961 and 1964, culminating in a first flight in October 1964.[1][2]
The Prue IIA has a 60 ft (18.3 m) wing that employs a NACA 63-618 airfoil. The aircraft is of all-metal construction and seats two in tandem under a long single-piece canopy.[1][2][4]
Only one Prue IIA was ever built.[1][2]
Operational history
The Prue IIA was used to set several multi-place glider records. It held the world out-and-return record of 366.88 mi (590.44 km) for a period of six months in 1967. A second world out-and-return record was set in 1972, flying 425.3 mi (684.5 km) from Pearblossom, California. In 1967 it was also flown to a world multi-place declared goal record of 322.35 mi (519 km).[1][2]
The IIA was removed from the Federal Aviation Administration aircraft registry on 16 March 1989 and now belongs to the National Soaring Museum.[1][3]
