Skandinavisk Aero Industri

Skandinavisk Aero Industri A/S (abbreviated SAI; English: Scandinavian Aero Industries) was a Danish manufacturer of aeroplanes that existed between 1937 and 1954. The company was founded by technician Viggo Kramme (1905–1984) and engineer Karl Gustav Zeuthen (1909–1989) and based in Copenhagen.

Founders	Viggo Kramme Karl Gustav Zeuthen
Defunct	1954 (1954)
Fate	Shut down operations due to unprofitability
Headquarters	Copenhagen , Denmark

The company's aeroplanes were labelled "KZ" for Kramme and Zeuthen, the first being the KZ I from 1937. The KZ IV was built as an ambulance plane for Zone-Redningskorpset and introduced in 1944. Post-war sales never reached the company's expectations, and production turned unprofitable in the early 1950s, driving the company to shut down. In total, about 200 planes were built by the company.

A number of the KZ planes have been preserved. As of 2005, Dansk Veteranflysamling (The Danish Collection of Vintage Aircraft) exhibits a specimen of each of the 11 aircraft models manufactured by the company.
