HEDP - Must admit I don't follow your logic.
1. A (cheap) charter aircraft organized by DTMA cannot get to MPA due breakdown/fog.
2. The already stretched RAF Tristar Sqn is asked to rescue the service and tries it's best to do so.
3. A good proportion of the FI garrison waiting to get home are RAF personnel.
And you say:
I do find it a tad rich that the RAF can bring their dets all this Xmas spirit while the other half crashes and burns
- based on the fact that some RAF personnel (who have absolutely nothing to do with the South Atlantic airbridge) are making the effort to have a "celebration" of sorts at Basra.
I know the RAF transport service often disappoints , but I think you are looking for fault where none exists.
Merry Chrimbo.
