The museum's collection includes three other aircraft which are parked outdoors around the edges of the museum parking lot: a
Boeing 757-200 painted in the 1980s livery, registered N608DA (ship no. 608, manufactured in 1985), a McDonnell Douglas DC-9-50 registered N675MC (ship no. 9880, built in 1975), and first ever
Boeing 747-400 produced for passenger transport, registered
N661US (ship no. 6301).
Delta Ship 6301 and the 747 Experience The most significant aircraft in the outdoor collection is Delta Ship 6301 (N661US), the first production Boeing 747-400. Originally used for flight testing by Boeing as N401PW, N661US was delivered to Northwest Airlines on December 8, 1989. On October 9, 2002, N661US was operating as
Northwest Flight 85 when it had to make an emergency landing in
Anchorage while on its way to
Tokyo from
Detroit for a rudder malfunction. When Northwest
merged with Delta in 2009, N661US became Delta Ship 6301 and continued passenger operations for Delta until it was retired on September 9, 2015, having logged more than 61 million miles of flight over its lifetime. The following April, the jumbo jet was moved across two streets from a parking spot on the tarmac at Atlanta Hartsfield-Jackson International Airport to its permanent home in the museum parking lot. Much as in the
Spirit of Delta, museum visitors enter the 747-400 via stairs and an elevator, proceed through the intact first class cabin, then through the economy section, part of which has been converted into an exhibition space, where the
aft pressure bulkhead is visible. Visitors are also able to walk on a walkway that runs over part of the wing, protected by railings. In addition, the cargo hold has been emptied and the cabin ceiling removed so that visitors can look down from the upper deck through the lower deck and cargo hold to see the entirety of the aircraft's massive cross-section. ==Collections, exhibitions, and facilities==
