Please note that there is a special lightmap included. The light inside the cabin during the night flights is different from the usual light that comes from a plane flying at night. This is due to the large number of computers and monitors onboard this flying astronomical telescope observatory. The package also includes a flightplan for the plane, to get it flying.
