Bombardier's all-new CSeries takes inaugural flight

MIRABEL, Quebec, Sept 16 (Reuters) - Bombardier Inc's CSeries jetliner took flight for the first time early on Monday, the culmination of a $3.4 billion development program showcasing the first all-new designed narrow-body plane in its class in decades.

The CSeries, which Bombardier says will be the world's quietest commercial aircraft, is Bombardier's big gamble to break into the hyper-competitive, larger aircraft segment currently ruled by Boeing Co and Airbus.

The white and blue CS100 test aircraft took off from outside the Bombardier plant in Mirabel, Quebec, at 9:54 a.m EDT (1354 GMT) in front of a crowd of employees, media and spectators.
