Trim Stab,
How do you know these evacuations will be for free, do you appreciate the size of the bill that USA presented to Kuwait some years ago?
As far as I'm concerned, as a UK taxpayer, I'd prefer my money be spent on aircraft and personnel I am already paying for rather than those aircraft and personnel sit idle whilst further expenditure is incurred paying for someone else's aircraft and personnel, i.e. I'm already paying these peoples salaries and I'm not prepared to pay your salary also!!!
Hopefully the MoD will spend so much money in the region they won't be able to afford the 200 million required to scrap the Nimrods.
