The last Boeing 747 to ever be built has changed hands in front of thousands of people who wanted to say goodbye to the iconic widebody plane. Customers, suppliers, celebrities, as well as current and former employees — including the original staff known as the "Incredibles" who built the first 747 — gathered at the company's Everett factory to witness Boeing delivering the plane to Atlas Air Worldwide. The event marks the plane's end of production since it was first built in 1967.
