Boeing 747 refueling SR-71 Blackbird
Here is what must have been a rare event; a 747 tanker refueling a SR-71 Blackbird. I don’t know much information about 747 tankers. If anybody has information about 747 tankers I would love to hear from you. I would especially be interested in photographs of the boom operator’s compartment, controls, and panel.

SR-71 Refueling
This image was taken in 1984 with pilot Les Dyer at the controls of the sleek Mach 3 SR-71 Blackbird. The KC-135Q was a specially modified version of the KC-135 that could separate its body tank fuel from the wing tank fuel so that it could carry the JP-7 fuel that the SR-71 required. Reengined KC-135Qs were redesignated KC-135T.
