The 777 aircraft has become one of Boeing's most popular aircraft since it was first built in 1995.
It is a very wide and extremely modern high-tech plane that Boeing calls the "backbone and workhorse" of the long-haul fleets of many airlines.
Boeing has built more than 1,000 777s.
U.S. federal officials say the plane had a nearly perfect safety record before last year's crash of an Asiana Airlines flight in San Francisco, in which three people were killed. Pilot error is suspected in that accident.
