The airline says its 10 DC-7Bs had a lounge in the back of the cabin and "brought luxury to the skies." The DC-7B was a longer-range version of the DC-7.
The interior of the DC-7B was decorated in tan, white, aqua and turquoise fabric and leather accented with gold and silver, with gold window curtains depicting scenes along Delta routes, according to the Delta museum's website.
Delta retired its last DC-7 in 1968 as newer jet engines rose in prominence.
Mechanics in Coolidge, Ariz. repaired Ship 717, replaced engines and ran tests to prepare it to make the trip to Atlanta.
In a written statement, Grantham said he was happy “to see the DC-7B going home to be celebrated and immortalized at the Delta Flight Museum.” The museum is located next to Hartsfield-Jackson and Delta’s headquarters, and has a collection of historic planes including a Boeing 747.
