I'm guessing that the RAF wanted an excuse to test out their reaction time and had a word with air traffic for a heads up next time there was a minor incident such as yesterday,
I used to rely on gate staff, handling agents and cabin crew to screen these idiots from boarding. If there was any doubt then they would not be carried on my aircraft. Problem lies in the availability of booze 24/7 allied to the fact that the first thing the airlines do is offer passengers alcohol regardless of the time of day. I never had to divert for unruly pax but on numerous occasions I made sure that they were met with friendly local police whose modus operandi may not have been quite as politically correct as in the UK !
