wub,
I think you might finally be somebody with hard evidence that I am not mad. I have always been adamant that I saw the B1-B doing extraordinary things at Mildenhall ('93 I'm sure was the last time I was able to get there - the year they had the SR-71 making transonic passes and 6nm turnarounds for another go!!!
), but it had reached an altitude beyond any accurate visual capacity with the MK1 eyeball, and above some thin stratus to be totally sure. Something like a half loop with a roll off the top at something beyond 5000' I reckon. Sound familiar?
