He seems to think he's always right. Here is what was origionally said to back his side up, one being no markings on the plane. No tail stripe (telling you where its based out of), no USAF tag near the cockpit, and no stars on the wings on body. Also the nose black paint is wrong. Though this could be a forgien plane, however i dont recognize the flag on the tail.

Those are 4 engine planes, probably in the neighborhood of 160-180db of sound. Listen to how loud the guys are, and that plane was what? 200 yards away max, it should have been a lot louder. I have flown next to these guys, a squadren of them are based at grand forks AFB and ive been 500ft above them crossing, and i could hear them at that, it was deafening even over my engine.
And also wake turbulence. He is probably what 50-100ft off the ground? Wake turbulence is most pronounced when low, slow, and heavy. The KC is a heavy(even classified as a heavy for ATC), and is pretty slow there, considering it tops out over 500mph. Look at the desert, no dust, none of the trees move. The vorticies produced by that plane would have kicked up a lot of dust and there was nothing.
**Edit**
On closer look, it looks like that tail flag is of the Swiss Air Force. Looking on Wikipedia, there are currently a few countries that operate KC-135's, the US Air Force, Australia, Brazil, Canada, France, Israel ,Italy, Morocco, Singapore, Spain, South Africa, Turkey, & Venezuela. Other models were sold to many other countries, but those are the only ones using it as a tanker. And the one in the shot is a tanker, as you can see the refueling boom.
Also, The KC-135 was modified to the KC-135Q/A to serve the blackbird, only 56 were made.
