This Pilatus PC-12 turboprop N21AU landing at Portland #KPDX would probably go mostly unnoticed... except for its radio callsign Boeing 21AU. This is a crew transport coming to pick up the test pilots from Boeing 508. It will take them back to Boeing Field #KBFI in Seattle where the flight test base is located. Either this plane or a Cessna 208 that Boeing flies for similar purpose shows up when planes are entering or exiting the PDX paint hangar. #aviation #travel #avgeek #PNW
