This revolution in jet transport started with the CRJ-100 in 1992. In
1996 the first deliveries the the succesfull CRJ-200 started.
All of this thanks to Bill Lear, founder of the Learjet. The lear jets
were small business jet aircraft, of which the production started in
the 1960ies by Bill Lear. Then Bill had the idea of a jet with a larger
fuselage, so that passengers would be able to stand up inside the
cabin. Also he used a supercritical wing on the aircraft. This business
jet became the Challenger. The Challenger business jet was an
independent design of Bill Lear in 1976, and production started a few
years later. Bill died in 1978, but this ideas continued to inspire.
Canadair and later Bombardier, used the Challenger business jet design of Bill Lear to develop a 50-seater regional jet.
