The Short SB.1 was a British tailless glider designed by David Keith-Lucas and Professor Geoffrey T.R. Hill. Built by Shorts as a private research venture to test the concept of the aero-isoclinic wing, it was the first aircraft to incorporate this feature.
It was in effect a one-third scale glider version of Keith-Lucas' ambitious preliminary design P.D.1,[1][2] intended to meet the Air Ministry's (V bomber) specification B.35/46, which was the basis for the Avro Vulcan, the Handley-Page Victor and the Vickers Valiant.
