"Didn't see flightplans for it though - or certainly not with an AWC code.
Could it be flying without a published flightplan, such as Air Force One has done in the past?
I believe the aircraft is due back to LHR in the early hours of Saturday morning."
Can anyone who is in the know clear up the flightplan thing? I know that BA Charters for our VIPs usually have published BAW flightplans.
It was flying on an AWC code, but as you rightly guessed, it was flying on an unpublishsed flightplan, for obvious reasons.
I hope that helps.
