The former American Airlines B727-223, N874AA, at Boeing Field in Seattle, now owned by the National Airline History Museum, Kansas City, Mo.

In early 2015, in preparation for the construction of its giant new Aviation Pavilion, Seattle’s Museum of Flight moved its Boeing 727 (formerly American Airlines N874AA) from the parking lot on the west side of East Marginal Way where it had been displayed along with other large aircraft. Instead of being towed to the museum’s air park with the other planes, it was towed all the way across King County International Airport (also known as Boeing Field) to a parking stall. Rumors swirled that it was headed for a new home, an unnamed museum in the Midwest.

And there it sat, and sat. And sat.

On March 3, the mystery was solved when John Roper, the executive director/board member of the National Airline History Museum (NAHM) in Kansas City, Mo., signed the transfer paperwork alongside Museum of Flight CEO Doug King and COO Laurie Haag, officially transferring ownership of the aircraft to the Midwestern museum.

The elderly 727 now has a dedicated Facebook page, and, as of this week, the electrical systems were in the process of being activated and checked in preparation for the aircraft being flown to its new home. Roper said that, as long as the engines are sound, his goal is to get the plane to its new home in Kansas City by May 1.
