Timothy,

Thanks for the additional references. The fellow who wanted to bring the Wing Derringer back into production by buying the Type Certificate wanted to enlarge it from a two-place to a four place aircraft, not exactly George Wing's concept at all. Furthermore, a new Type certificate probably would be required if enlarged.

John Thorp designed a Twin Skooter, his 17th aircraft design which was the basis of George Wing's development of the aircraft into the Wing Derringer. To my knowledge, no twin Skooter ever went into production.

The prototype Wing Derringer had two 115 Hp engines and was lost in flight testing in the Pacific ocean off TOA, if memory serves me. The FAA granted Type certificate A9WE for the Wing Derringer on 20 December 1966. BY 1967 four aircraft were built including the prototype and static-test aircraft. Plans called for the design to be sold to the Wing Aircraft Company that intended to contract for production with an experienced midwest airframe manufacturer.

More about those rivets.....

Hi-Shear Corporation built structural fasteners for many aircraft programs. To name a few-Boeing 707, 720, 727, 737 and 747 series, the Douglas DC-8 stretched series and the short haul DC-9. Military structural fastener contracts were for the McDonnell F-4, the Northrop F-5, Lockheed C-141 and C-5A, Bell Hueys and Sikorsky helicopters, Grumman S-2A, A-6A, E-2A, C-2A, OV-1 and General Dynamics F-111 series.

Company trademarks and patents for aircraft fasteners were Hi-Shear rivets, Hi-Lok, Hi-Torque, Hi-Kor Blind Bolts, Six-Wing Bolt and Nut with mating driver sockets, Sectional Blind-Sert and pneumatic or other tools for fastener installation.

Their Ordnance program offered Gas-generating Power Cartridges, Separation Nuts, and Deep-Submergence structure-release systems. Their Separation Nuts were used in NASA's Jet Propulsion Laboratory's Hughes Surveyor landings on the moon. Hi-Shear Corp. had over 257,000 square feet in over 12 buildings at Torrance Airport TOA.
