Rocket hole

High up on the ceiling is this small hole, which no one would ever notice or think to question. In fact, however, it is there because of a NASA promotional program in the late 1950s, when the government was trying to raise awareness and support for America's space program, which brought a rocket to the concourse. However, the measurements of the rocket turned out to be wrong, and it was six inches too tall for the the ceiling. So this six-inch hole was punched in the ceiling to accommodate the rocket.
