A recently-restored Boeing 727 prototype sits on the tarmac before its expected first flight in 25 years, Friday, Feb. 26, 2016, at Paine Field in Everett, Wash. The three-engine, Boeing 727-100, N7001U, flew from 1963 to 1991, logging 64,495 hours of flight time and about three million passengers for United Air Lines. Weather permitting, the jet is expected to make its final flight, of about 15 minutes, from Paine Field to The Museum of Flight in Seattle Wednesday, March 2. Upon landing, the 727 will taxi directly into the Museum's parking area, where the engines will be shut down for the last time. (AP Photo/Elaine Thompson)
