LJ, I am amazed by the number of people on here who would like us to think of them as "experts" and their comments on this topic. This stuff happens every day (although not always with a supersonic transit). I think my personal record (not all that long ago) was 4 scrambles plus another 3 "Q to cockpit" in a 12 hour period just to deal with civilian aircrew who forgot/couldn't be bothered to change M3/radio frequency etc.
