Ship 608, is a Boeing 757-200 built in 1985 with Pratt & Whitney PW2037 engines. From 1985 to 2013, the aircraft flew domestic routes for Delta, including service with Song Airlines, Delta's innovative low-cost carrier, from October 2005 to May 2006. Ship 608 retired from service on October 1, 2013, and was stored at the Pinal Airpark in Marana, Arizona. She came out of storage and joined the Delta Flight Museum on April 27, 2014. Today, Ship 608 is part of the retired Delta fleet parked by the Museum Gate that welcomes our visitors. (Please note that direct access to Ship 608 is restricted as the plane is outside of the designated Museum security area. Signage for the plane is located near the B747 plane.)

The Boeing 757-200 sported "new technology wing and engines to give the best fuel mileage of any standard-body airliner" in 1982. On a 500-mile flight, the 757-200 provided approximately 45 percent better fuel efficiency than the Boeing 727 it replaced in the Delta fleet. With its new wing design, fitted with double-slotted trailing flaps, full-span leading edge slats and high thrust engines, the 757 could cruise at a higher altitude than the advanced 727-200, allowing greater fuel savings and use of higher airways.

Delta was launch customer for the Pratt & Whitney PW2037 engine, used on Ship 608, which provided 10 percent more fuel efficiency than earlier Pratt & Whitney JT10D engines offered on the 757. Note: The 757 was initially launched with Rolls Royce engines.
