Many years ago (about 25) I was flying south alongside the A1 (the Brits will know it) between Grantham & Stamford when a Vulcan passed about 100ft below me, heading North, talk about "brown trousers" - put me in a bit of a spin (literally) but nothing was done when I reported the airmiss
Never liked the things since.

Do get a buzz as the Battle Of Britainicon Flight pass over us most weekends in the summer its based about 10 miles away - and as we are based alongside an old WW2 Lancaster airfield the Lanc does a low flypast everytime (about 250 - 300ft, occasionally considerably less and we get a wave from the guy up front). Great noise and everyone looks up - unlike the Typhoons - nobody looks at them.
