The Bombardier CRJ700, CRJ900, and CRJ1000 are a family of regional jet airliners designed and manufactured by Canadian transportation conglomerate Bombardier; the trio of aircraft has been collectively marketed by the company as the CRJ Series. Their design was derived from the smaller CRJ100 and 200 airliners.
During the 1990s, Bombardier initiated development on the CRJ-X, a programme to produce enlarged derivatives of its popular CRJ100/200 family. Officially launched in 1997, the CRJ700's maiden flight took place on 27 May 1999; it was soon followed by the stretched CRJ900 variant. Several additional variants of the type were subsequently introduced, including the CRJ550 and the elongated CRJ1000. While production of the smaller CRJ100/200 range was discontinued during 2006, the larger CRJ Series models have continued to be produced into the 2010s. Competitors have included the Fokker 70/Fokker 100, the BAe 146 family, and the Embraer E-Jet family.
