Arrival of a Voyager at Brize Norton on the last working day of 2011 would be somewhat reminiscent of the desperation of the Soviet Union when it managed to rush the Tu-144 into the air on 31 Dec 1968 'the year before Concorde'....
I suppose it'd allow ATr to claim that the aircraft was delivered 'on time' at Brize - i.e. in late 2011...
But as to whether or not the RAF has accepted it from ATr; well, that would be a somewhat different question!
When the first VC10Ks arrived at Brize in 1983, they too were pristine - and stayed that way for quite some time before they had the usual grubby handprints in the cabin and DMS shoe scrapes all over the exterior fleet embodied by lazy lineys. Which was a great shame as the first 101 Sqn GEs used to keep 'their' aircraft looking immaculate inside and out.
Perhaps ATr will insist on higher standards of aircraft husbandry than the usual RAF filth, grime and bodge tape standard.
