I bicycled to Portland Int'l Airport #KPDX for a closer view of this unpainted Boeing 737 MAX8. Coming from Renton WA #KRNT where the 737 final assembly line is, I suspect this was the very first flight of this aircraft, known as the "B1" flight since it's the first flight done by Boeing test pilots. (A later pre-delivery flight with customer test pilots is called the "C1" flight.) Boeing has a paint hangar in Portland so some new planes fly here on B1 to get painted. #aviation #avgeek #PNW
