China's first homemade regional jet, the ARJ21-700, rolls off the production line at its assembly factory in Shanghai on December 21, 2007.

Powered by a turbofan engine, the 90-seat ARJ-700 jets have a maximum range of 2,000 nautical miles. Their maiden flight is scheduled for March 2008.

Manufacturers said at the rollout ceremony that they had received orders for 171 ARJ-700 jets and the first delivery to customers was expected in the third quarter of 2009.
