Regarding the "Operation Intercept". I remember being shown it at MPA as part of arrival procedure. I found it briefly interesting but when they showed the VC-10 flight deck it became a little sad. Reason the chap in the RH seat had only recently passed away, he was a Capt on 101 at the time and probably one of the better "touch/feel" pilots. One story was whilst doing fighter assim, the fighter could never find the "brown bomber". Why, because the combination of pointing the nose towards the fighter and the angle of attack of the VC-10K was raised sufficiently so that the wings blocked the compressor intakes making the good old VC-10 difficult for the fighter's radar to find it.
