There seems to be some confusion here as to who has airworthiness responsibility for these aircraft, MAA or CAA. Also, there is clearly some confusion between "Airworthy" and "Serviceable," I don't know too much about the MAA world, but in the CAA/FAA world these terms have very different meanings and are NOT interchangeable. The partial statement in Post #1, i.e. “Work has started to make them serviceable for flight already. Just enough to get them over the pond. Nothing to do with the mission side.” is probably correct.
