According to the RIAT show programme, the USAF plan to move their RC135's to Fairford. As Waddington seems to be unsuitable for Rivet Joint to use with full fuel, one suspects the RAF fleet will follow.Looking back to the 1980's part of the European tanker task force was based there so it hardly takes a genius to figure out that a couple of TDY tankers could join the aircraft there - there's plenty of ramp space.
Harking back to Greenham Common, this was originally mooted as the base for the TTF in the 80's. That was until the locals got uppity and started a 'keep it quiet/closed'
protest. Then HMG 'suddenly noticed' that a certain government facility just down the road, making things that go bang, was right under the flight path. This gave them an honourable out to move the nasty noisy jets to Fairford.
