This stair case leads to the bed room prop. We had to advance a hose line up these steps. It was a tight squeeze but we mad it up it was crazy goning up a sprial stair case in the dark in full gear and draging a hose. If you look to the left of the stairs close to the top you can see one of the cameras. There are cameras all throuhg the training tower so the instructors in the control tower can watch everything goning on.
