At the same time the number of people participating in soaring had increased and there was a clear market for a low cost sailplane. [2] Design goals for the new glider included: [2] available as a kit; small and light weight for ease of storage and construction; rugged design with a focus on pilot protection; launched by autotow, winch and aerotow
The SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1] [2] [5]
(The Boeing 767 in the Gimli Glider incident achieved a glide ratio of only 12:1). The loss of height can be measured at several speeds and plotted on a "polar curve" to calculate the best speed to fly in various conditions, such as when flying into wind or when in sinking air. Other polar curves can be measured after loading the glider with ...
The sailplane is attached to one end of 800 to 1,200 metres (2,600 to 3,900 ft) of cable and the winch rapidly winds it in. The sailplane can gain about 270 to 910 metres (900 to 3,000 ft) of height with a winch launch, depending on the headwind.

The Schweizer SGS 1-35 is a United States 15 Meter Class, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. [ 1 ] [ 4 ] The 1-35 was first flown in 1973 and a total of 101 were completed by the time production was completed in 1982.
A 1-23, flown by William Ivans, set a world altitude record for gliders on 30 December 1950, reaching a height of 42,089 ft (12,840 m). [6] 1-23Ds were flown by Paul McCready to win the 1953 US Nationals and to set a distance record of 455.5 miles (733 km) by Joe Lincoln. Lincoln was awarded the Barringer Trophy in 1960 for that distance flight.
The 2-32 was designed to be the highest performance two-place glider available, when it first flew in 1962. The 2-32 has been used as a tourist glider, trainer, cross-country and high-altitude sailplane and has set many US and world records. A total of 87 aircraft were completed. [1] [3] [4] [5]
