Assuming flaps down, 8 engines, a 200 foot line-up distance and no wind, a

Now you know why airports with runways exceeding 8,000 ft. were considered
nuclear targets during the Cold War...



There's a story, which I cannot verify, that the RAF took a Vulcan
across the Atlantic to a bombing competition. They watched the B52s
lumber away and decided a bet was in order. I don't know what
base/how long the runway but the bet was that a fully loaded Vulcan
could make 5000 feet altitude over the "far" end of the runway from a
standing start. The Vulcan won (I think a case of good whisky).

Having seen a few Vulcans fly, I can believe this might well be true!
