 FACT: As the aircraft prepares to land at Andrews (just before  credits) the aircraft commander tells the passengers that they are  being turned out for runway 39. There is no runway 39 at Andrews or  anyplace else. Runways are numbered (in multiples of 10) to the  closest magnetic heading aligned with the runway when landing.  Runway 9 points east (090 degrees); runway 24 to the southwest (240  degrees). A runway that "points" north would be Runway 36
