There has been a KC-135R circling over DC all day, and it is curently still there circling (they swapped aircraft, this is the 2nd KC-135R from this morning). The C-130's have been silent, so I assume the troops are still there. I don't have any idea what this represents, but I thought that I would share. Possibly the troops will remain? What is the big KC-135R doing? it must have some kind of activiy monitoring systems?
