The Open House at Portland International that the Redhawks held was not the only thing going on that morning.  While we were checking out the F-15s, a bunch of ground crew were at work out on the ramp area.  They were setting up spots on the ramp for some incoming planes.  As soon as I saw the ladders being carried, I could see that they were not for F-15s.  They looked a lot more like F-16 ladders.  The crews carried them out in a variety of manners but this person seemed to have a more relaxed way of moving a ladder around.
