Interesting about the Tornado, EGSC (Cambridge) ATC had been complaining about the violation of the approach to R23 by low flying Tornado's, which fell on deaf ears at high command until an Air Vice Marshall was on deck of an L1011 RAF Freighter 10 miles out on the centre line R23 (pre ILS at Cambridge) when low and behold left to right 500ft approx came another offending Tornado, needless to say it hasn't happened again since, probably because all the aircraft are constantly U/S nowadays.
