Valid point, yes... Why not start a thread about it!
I've taken the highly unusual step, for pprune, of actually finding some facts on the subject. With respect to what was for me the major issue, that once a fighter was launched it continued to intercept and force a diversion even if comms were restored. I have discovered that, contrary to some of the headmasterial posts here, that isn't the case and in at least one instance a Typhoon held over Northolt without intercepting after a Glasgow bound B757 which had lost contact at the French FIR had come back on air. Perhaps those who posted to the contrary weren't aware of this or felt, incorrectly, the info was classified?
I also discovered that the Frogs carry out very many more interceptions than the UK...suggesting that the "self justification" issue is very much alive but in pointing the finger at the UK authorities we've got the wrong target.
