Bombardier CRJ100/200

The Bombardier CRJ100 and CRJ200 are 50-seat regional jet airliners designed and built by Bombardier Aerospace between 1991 and 2006, the first aircraft of the Bombardier CRJ family. The programme began in 1989 as the Canadair Regional Jet, a stretch of the Challenger 600 business jet, and the first prototype flew on 10 May 1991. Lufthansa was the launch customer, and Canada's first jet airliner to enter commercial service was introduced in 1992. Two GE CF34 turbofans are mounted on the rear fuselage. The CRJ200 differs from the CRJ100 mainly in its more efficient CF34-3B1 engines, which give lower fuel consumption and a higher cruise altitude and speed. Production ended in 2006 but many remain in service, and in 2020 Mitsubishi Heavy Industries bought the whole CRJ line. The type was later stretched into the CRJ700 series.
