This photograph from 1966 shows the Zero Gravity Facility at Lewis Research Center, now known as John H. Glenn Research Center at Lewis Field. This tunnel view looks up from level 5. In this experiment, the tower dropped 460 feet and allowed scientists 5.18 seconds of zero gravity. By comparison, the Washington Monument is 555 feet tall.
