I didn't know!
For a short time, perhaps.
IMO, they just don't fit Delta. But what a history.
MontanaFL said - I think DL had them for a short period of time while waiting on the L-1011 to come into service. DL at one time had all three jumbo's (B-747, DC-10 and the L-1011) in their fleet.
I know this has been discussed many times, but I have always believed that the term Jumbo was only in reference to the 747. The DC10 and TriStar are widebodies.
I don't think there is a formal definition of Jumbo out there, so I guess the DC10 and TriStar could be included, but it seem to be linked mostly to the 747.
