SEATTLE (AP) — Boeing bid farewell to an icon Tuesday: It delivered its final 747 jumbo jet. Since it debuted in 1969, the 747 has served as a cargo plane, a commercial aircraft capable of carrying nearly 500 passengers, and the Air Force One presidential aircraft. It revolutionized international travel. But over about the past 15 years, Boeing and its European rival Airbus have introduced more profitable and fuel efficient wide-body planes. The final plane is the 1,574th built by Boeing in the Puget Sound region of Washington state. Thousands of current and former Boeing workers gathered for a ceremony marking its delivery to cargo carrier Atlas Air.
