The first space shot to be built in the United States was the Spaceshot at D&D Adventure, a now defunct family entertainment center.
In the loading position, the seat carriage is at the base of the tower and the piston is at the top of the pipe column.
As the piston moves down, it pulls the cable downward over the pulley at the top, propelling the seat carriage up the outside of the tower.
Upon exhausting the air from the pressure system, the carriage descends, drawing the piston back up the pipe column.
As the piston moves up, the air inside the pipe column alternately compresses and expands, causing the carriage to bounce several times.
