I duck in avoidance of these damn KC-135s all day long here in Wichita. They do pattern work like cheap Cessnas. I do not have the lens arsenal that you have, but I'll see if I can grab a few sunny shots of these birds doing pattern work at McConnell AFB fairly soon. I have been working through in my mind's eye a good vantage point for quite some time now, and it is not an easy thing at McConnell.
