BARKINGMAD
Xcitation: please read the account of how Uncle Sams military and allegedly his ATC organisation behaved on Sept 11th and then say you are confident that the scramble scenario would occur "TopGun" style in this corner of the world as you believe it should have.
It's nearly 13 years since that event, and it is probable that until this week most military setups are not really on alert like a coiled spring as the public would like to imagine.
Within weeks of 9/11 a small turboprop aircraft was discovered straying in the London TMA without a single F3 Tornado launched in response, not exactly trumpeted by the authorities at the time.
Yes - and a LOT has changed since then. I can personally recall hearing two air intercept events whilst flying in European airspace, and shared a rather somber beer with the captain of one of those aircraft, who had missed the fact that he had flown out of French CTA and into somebody else's with his VHF 1 inadvertently flipped to a previous frequency!
Bearing in mind they were following their flight planned routes and transponding appropriately, what do you think would have happened if they suddenly went OFF flight plan, disabling TX and ID kit, and dropped low level?
This is the very raison d'être of aviation security bodies and airforce fighter/interceptor "assets".
