The Tweed GT-1 is an American high-wing, FAI Open Class single seat glider that was designed by George Tweed Jr.[1] Design and developmentThe GT-1 was built in concert with the Whigham GW-1 as both builders shared ideas and tools. The GT-1 first flew in 1960.[1] The lower part of the GT-1's nose was constructed from a drop tank, with the upper part fabricated from fiberglass that was laid up using the drop tank as a mold. The landing gear is a retractable monowheel. The aircraft was initially fitted with a bubble canopy. Later the fuselage was modified to allow a more reclined pilot seating position and the canopy replaced with a more streamlined one. The modifications added {{convert|200|lb|kg|0|abbr=on}} to the glider's empty weight and the gross weight was raised {{convert|100|lb|kg|0|abbr=on}} in partial compensation. The GT-1's {{convert|51|ft|m|1|abbr=on}} span wing employs a NACA 43012A airfoil. The initial glide ratio was 29:1, but extensive work gap-filling and contouring the aircraft raised this to 33:1.[1] Only one GT-1 was built and the aircraft was registered in the Experimental - Amateur-Built category.[1][2] Operational historyThe GT-1 was entered in the 1960 US Nationals, but, as the designer termed it, the aircraft "proved to be a victim of technical obsolescence" and it did not place well. Both the designer and Jack Green did however complete their gold badges in the glider.[1] By 2011 the aircraft had had its Federal Aviation Administration registry revoked and the aircraft likely no longer exists.[2] Specifications (GT-1 later configuration){{Aircraft specs|ref=Soaring[1] |prime units?=imp
