The Schweizer SGP 1-1 is an American amateur-built single-seat high-wing primary glider that was designed by Ernest Schweizer and constructed by the Mercury Glider Club between 1929 and 1930. The 1-1 became the first in a line of 38 glider designs that the Schweizers created and the first of over 5700 aircraft built by them. A replica of the original 1-1 was constructed by a group of volunteers led by Ernst Schweizer in 1989 to celebrate 50 years of Schweizer sailplane construction.
Made by Mercury Glider Club.
