So I actually have an answer to your original question.
It was a KC-135 and a two ship of Eagles from the Guard unit in Fresno. A dude I was at an assignment with a few years ago was in the Eagle two ship and posted the photos on his Facebook 4 days ago. Looked like they were getting some shots over the Bay and Golden Gate Bridge. I haven't talked to him since that assignment but I can ask him if the photos are shareable.
Public Affairs photo shoots over national landmarks are pretty common honestly and tankers are the best way to take them.
