FSX Fictional NASA Boeing 737-800, non winglets. This is a repaint of the first 737 made by Boeing and then used by NASA to test virtual cockpits, windshear and glass cockpits based at NASA Langley Research Center. N515NA (Fat Albert) is now stored at the Museum of Flight Airpark in Seattle. Textures only for the payware PMDG model. By Michael Lim.
