Corrected entry: When the crews board the shuttles, it is daylight, but when they are about to take off it is dark. Seeing as Truman told them they would be taking off at 8 am, it doesn't really make sense that it should be dark.

Correction: When Truman is explaining the mission (during which he describes the "Roadrunner Thrust Maneuver") he states that they will be taking off at 6:30 p.m. Depending on what time of the year it is, it could be dark at the launch.
