The result—the Vehicle Assembly Building, the V.A.B.—is one of the man-made wonders of the world, but at the time of Apollo it was celebrated mostly for things that weren’t true. The most widely accepted legend was that the V.A.B. was so huge that it had to be air-conditioned to prevent clouds from forming inside. Wrong on both counts: The V.A.B. was not air-conditioned, and clouds didn’t form anyway.
