Bombardier Challenger 600

The original "Challenger" that spurred a family of private aircraft billed as "the best-selling business jet platform of the last decade,” the Bombardier Challenger 600 began life as a proof-of-concept business aircraft design from American aircraft pioneer Bill Lear that featured a widened fuselage allowing a "walk-about cabin," and a supercritical wing offering impressive climb and cruise performance at lower thrust settings. The design was subsequently purchased by Canadair, the predecessor to Bombardier, in the late 1970s. Canadair further refined the design and certified the aircraft in 1980.
