The most notable confirmed surface to air missile attack on a civilian airliner that I have heard of was done by the US Navy. I also believe Israeli fighters shot down a Libyan 727 in the 70's, Korean Airlines have had TWO shoot-downs plus an Italian DC9 was also shot down by what turned out after years of denials to have been an air to air missile.
Whatever the colour scheme, surely the terrorists could work out which was which if they really wanted to -and even if they couldn't, would they care less?
