Having initially been slightly disappointed to 'only' have seen a KC-135 during my stop (successfully missing the morning's C-17), looking in Military Aircraft Markings now, this is listed as a KC-135R(RT) - Capable of being itself aerially refuelled it was one of eight to receive the conversion - a new one for me.
Are the only KC-135s flying in USAF service now KC-135R, T or R(RT) - or are there some other niche variants or sub-variants I'm unaware of?

Then on to Lakenheath, waiting for very little to happen after the Heritage Jet took the cable. After a while, two Strike Eagles launched (any help with the serial of the second appreciated, one had the large font number 301- they departed at 1256 and I'm also after the identity of the Lightning visible from the viewing area at this time). It was still quite foggy.
[Edit: F-15s were 301 and 209 whilst the F-35 was 5581 - With credit to andygolfer and slogen51]



Thanks for looking - any comments or constructive criticism welcomed.
