luigi... Thank you for your extreme rudeness, which sums up what sort of person you must be. Thankfully, ALL the ATCAs I ever worked with were polite, good-humoured professionals for whom I had extremely high regard.
My response to you was, I thought, good humoured. If you are really employed in ATC you should not have to ask such questions on here - talk to the ATCOs you work with or to Thames Radar or Heathrow on the phone. Best of all - go and visit TC and sit with the guys there. They'll tell you that no large jet aircraft is going to come down to 50 ft over Biggin Hill at night and military jets don't go bombing around the TMA beating up airfields either. They used to, but that's many years ago and they were always under ATC control..
