The troops you saw on Thursday went out on XLA8806 G-BOPB Boeing 767-200ER, which arrived as XLA006P, probably from either London Gatwick or RAF Brize Norton. This aircraft also wears their new livery. It arrived at 07:07 and departed at 07:55 according to the DTVA Group. It returned today as XLA8807 at 08:58 and left again at 09:55 under the same flight number.
Yes, the CIA route was popular, but it obviously didn't work for Ryanair otherwise they wouldn't have chopped it.
