MONTREAL: Canadian aviation giant Bombardier announced on Friday it has received an order for 20 of its Challenger 350 business jets valued at about $534 million. The small twin-engine jet can carry up to nine passengers and fly as far as 6,000 kilometres (3,700 miles) on a single tank of fuel. The Montreal-based company did not disclose the buyer. Bombardier has been struggling recently in its first foray outside of business and regional passenger aircraft and into the category of medium-range, single aisle jets, with the launch of its new C Series jetliner.
