The APA at Netheravon mostly use a Cessna Caravan, which I don't think produces contrails.
As for the GR4s, Im at the defence academy (not all promotions are good
) now so not too clued in to RAF Marham on a day to day basis, but there are a few possibilities, in that Salisbury Plain, Sennybridge and Lolworth Cove are all within that area, and Castlemartin ranges are on the south welsh coast. All the jets are fleet managed now, so Sqn markings and livery on the planes are not a good indicator of who is actually flying them now.
If they are working with JTACs on exercise, they will sit 'in the wheel' for quite a while whilst tracking a target on the ground. The pilots apparently get very bored doing this, as one demonstrated by spinning me round on my office chair to illustrate his frustration. Its mostly backseat action.
