RCH4606 USAF C-17 Globemaster heading to Osan AB SoKo from JB Elmendorf
This is heading in to pick up Potato's equipment from Seoul visit so we should see some movement from 82-8000 (the 747) that Potato is on heading to Tokyo soon
Those other traces represent the 747 and the C-32A that went to Seoul and the longer one is the Nightwatch AC that went to Kadena AB, Okinawa and will stay there until Potato and crew depart Tokyo
