Klapmeier brothers
The Klapmeier brothers, Alan Lee Klapmeier (born October 6, 1958) and Dale Edward Klapmeier (born July 2, 1961), are American retired aircraft designers and aviation entrepreneurs who together founded Cirrus Aircraft (as Cirrus Design Company) in 1984. Under the leadership of the Klapmeiers, Cirrus was the first aircraft manufacturer to install a whole-plane parachute recovery system as a standard on all its models—designed to lower the airplane and occupants safely to the ground in case of an emergency.
