The Schweizer SGS 2-33 is an American two-seat, high-wing, strut-braced, training glider that was built by Schweizer Aircraft of Elmira, New York. The 2-33 was designed to replace the Schweizer 2-22, from which it was derived. The aircraft first flew in 1965 and production was started in 1967. Production was completed in 1981. From its introduction until the late 1980s, the 2-33 was the main training glider used in North America.

The ICA IS-28 is a two-seat sailplane produced in Romania in the 1970s. An all-metal aircraft of conventional design with a T-tail, it was originally produced with 15-metre wings, but in 1973, production shifted to the IS-28B with 17-metre wings and numerous aerodynamic refinements. These included a smaller tail with decreased dihedral, decreased dihedral on the wings, and redesigned fuselage contours. This version first flew on 26 April 1973 and was subsequently produced in versions with flaps (IS-28B2) and without (IS-28B1). Around 100 had been built by the early 1980s, with a substantial number sold for export. On April 7, 1979, Tom Knauff and R. Tawse set a world record with the IS-28 B2 glider, covering a distance of 829 kilometres on a predetermined out-and-return course from the Ridge Soaring Gliderport in Julian, Pennsylvania.

The IS-28B2 is depicted in the film Escape From New York (1980)

The Schweizer SGS 1-26 is a United States One-Design, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. The SGS 1-26 enjoyed a very long production run from its first flight in 1954 until 1979, when production was ended. The 1-26 was replaced in production by the Schweizer SGS 1-36 Sprite. The 1-26 is the most numerous sailplane found in the US.

In October 1963 a special issue of Soaring magazine was dedicated to the 1-26. Harner Selvidge wrote:

“Much of the glamour of soaring lies in the realm of high performance, high aspect ratio open class sailplanes, but the backbone of the soaring movement in this country, and any other, lies in the local club operations. These are the weekend fliers who have fun around the airport, make some cross-country flights and enter local contests. For this sort of flying, the 1-26 is unexcelled.”

The Let L-33 Solo is a Czech shoulder-wing, single-seat, glider produced by Let Kunovice. The L-33 first flew in 1992 and remained in production through 2012, supplied as a ready-to-fly aircraft. The L-33 was a developed as the single-seat “natural step” for early solo students to fly after dual training on the two-seat LET L-23 Super Blaník.

For tow planes, NCSA owns two CallAir A-9 aircraft. These former agricultural, heavy duty single seat low wing aircraft are perfect for quick and efficient tows to any desired altitude.
