Cirrus Aircraft is a well-known aircraft manufacturer headquartered in Duluth, Minnesota. The two founders, brothers Alan and Dale Klapmeier, built a homemade aircraft in their parents’ barn in 1984. Shortly after it was built, the two brothers began flight testing the aircraft, which was called the Cirrus VK-30 kit aircraft, and eventually introduced it at the local EAA AirVenture air show in Oshkosh, Wisconsin, in 1987. Kit deliveries for the newly designed aircraft began shortly after. The Klapmeier brothers continued designing aircraft after the VK-30s introduction.
