Coincidentally, the vehicle assembly building (VAB) at Cape Canaveral became the world’s then-largest building in the world when it was finished in 1966. This historical photo shows the construction of the VAB, which stood at 525 feet and covered almost eight acres once completed. The VAB remains the final assembly point for the shuttle orbiter, external fuel tank, and twin solid-rocket boosters prior to shuttle launches. (U.S. Army Corps of Engineers photo)
