Note that the original caption that came with this photo said that the plane was dumping fuel prior to an attack run. While that was a standard procedure, the crew of Special Kay (64-17679) has pointed out that this doesn't make sense. The wing pylons are empty, so there are no bombs and the bomb bay doors are closed. Additionally, the USAF "Stars and bars" insignia is displayed on the fuselage, which was not something that remained visible during combat in Vietnam. Once arriving in-country the stars and bars were removed from the special operations planes. They also note that the left engine is feathered and not running. Based on all of these factors I agree with their assessment that this plane is definitely not setting up for an attack run. Richard Fulwiler points out that dumping the wing tip tanks is standard procedure for landing (according to T.O. 1A-26A-1, Section 2-15, Descent item #12). This seems like it is a landing exercise at England AFB.

664 over the Pacific in Dec 1966 en route to Thailand. Note that the plane still has the grey underbelly used on training planes in the US and the paint scheme still has the small serial numbers.

64-17664 is visible in the back right corner of the photo wearing a glass nose. The conversion to a recon plane happened after arriving in Thailand.
