Plugged in behind a VC10, Nav shouts look left 10, saw an F4G cross above the VC10 by about 500ft, closely followed by 3 trailers. Unfortuantely the #4 was about 10 feet (yes, 10 feet) above the VC10! My heart was so far in my mouth (and there was a little turbulence
so I was concentrating), that I didn't say anything and I'm not sure what I could have said to the VC10 as he was past so quickly. I assumed that they knew what they were doing, were visual throughout and were trying to be punchy, but then #4 rolls back left and I guess he must have seen the VC10, realised how close he must have come (had he seen it in the first place?) and the whole aircraft rocked left/right/left.
If he knew what he was doing, he was an arse, if he didn't then I don't think much of his lookout.
