I flew into PIT tonight, and I noticed that the main checkpoint has had one of its Rapiscan blue walls of ionizing radiation replaced with what looks to be a newer model with a protruding LCD screen similar to the ones installed on the L3 MMW machines. It used the name Intelliview, and the blue panels now have the chalk outside "I surrender!" pose. This installation occurred sometime within the last three weeks. I hope this doesn't mean the purchase of more backscatter machines for currently WTMD only airports because the TSA seemed to be moving in the direction of MMW+ATD only for new installations.
