First Boeing 727
While passing some time well wasted in YouTube, I came across a video posted by Australian Videographer, Paul Stewart, on the first Boeing 727-100 ever built.
Registration N7001U was a prototype that first flew on February 9, 1963 and was delivered to United Airlines on October 29, 1963 and was used for pilot training before entering commercial service. It would later be dubbed the 'Spirit of Seattle' until withdrawn from service in March 1991.
It was then donated to the Museum of Flight in Seattle, Washington, stored at Paine Field for restoration and repainted in its original livery.
Ken advised me of a website created by retired Boeing employee, Robert A. Bogash, with a very detailed description and photographs of the restoration.
