Re F-35, State of the art Stealth whatever my ar$e, by the time they write the 24 million lines of code or whatever that's required to make the thing fully operational (maybe not in my lifetime), some dyslexic 15 year old genius will have found a way to detect the thing in his bedroom anyway.... That's if the machine will have the reliability to exit it's aircon hangar in the first place..
Sorry for the rant and being off topic...
