Had a few takeoffs in 707s and a couple in KC-135s. Don't remember anything that unusual, but I wouldn't have known any better at the time. Did get to visit the boomer's position in the 135. With another ROTC cadet with his hand on the control, the boomer told him to move the refueling boom all the way to one side. Then told him to move it as fast as he could to the other side. I believe the next thing the boomer said was "You can hear the pilot cussing from here." This was a long time ago
