Daily mission from the ones at Fairford and they go out and come in on normal V/UHF airfield/area control frequencies.
Rarely plot on the free trackers, though Wednesdays mission as BLACK01 (frame 80-1083) was plotting on it's return to FFD, as they keep their Mode-S/C transponder off.
If you happen to be using PlanePlotter, which can also plot using Mode-A, then plotting them is straightforward (subject to normal requirement of sufficient receivers sharing the required raw data).
