Wb's SATCO - don't be such a poof! Back when men were men and F4s ruled Wattisham, we did many an intercept on the 'Norwich Flier' flogging its way from Amshterdam to Naarch Airport!
If the people-tube drivers want to operate in Class G, they should expect to be used as targets for the odd PI!!
And, err, my nav and I were once flying as SLF in an ancient F27 from East Midlands to Naarch after a long flog back from Turnhouse (they couldn't get in to Leeds Bradford) - only to be intercepted by F4s from our own sqn. Didn't think twice about it - perhaps because the rather nice cabin lady had earlier given us complimentary G and Ts of industrial strength!
