How about an idle Concorde that has been sitting around LHR 27L for quite a while. At least SOME of that is british isn't it??!!
At least it might be able to get him OUT of trouble as quickly (mach2) as he seems to get himself INTO trouble.
Plus he'll have the added advantage of waving at George W Bush as he overtakes him at FL490.
Would be one of the few times Blair would not be looking up (or sucking up to) Bush's tailpipe!
