FSX SAS Airlines Boeing B377. This is a repaint of the A2A Boeing 377 with COTS update. Scandinavian Airline Systems ordered four Boeing B-377's but did not take delivery, instead they went to BOAC. This paint is based on several artist concept drawings of the proposed livery. This is a repaint only and requires the A2A B-377 with COTS upgrade. By Paul Grubich.
