When I go through US immigration, as a crewmember for a US carrier and also as SLF with a UK passport, I have been pulled to one side occasionally for a closer look. Just as I start to get all prickly about it I remember a certain Richard Reid who also had a UK passport along with a bomb in his shoe! If the guy that drove the Egyptian 76 into the drink had waited until post 9/11 would he have chosen another destination? Who knows, but Im sure the folks that rightly or wrongly make these policies look at these things and try to do whats best. Another aviation based attack anywhere and we will all be up a gum tree!
