There is one "civilian" and "camouflaged" small plane on tarmac. They could be the 2 Skytrucks that are operated by USAF SOC 27th Special Operations Wing/318th Special Operations Squadron from Cannon. They were spotted going thru RAF Mildenhall, haven't much about whereabouts since.
They also could be Skyvans since the dimensions from GE seem to fit better, number of civilian operators operate them and they are used for skydiving.
