Two entirely different trains are shown; the first one has a rear-attached pusher-engine with a controls-end passenger-car in the front, while the second train has a regular locomotive in the front.
The screen caption describing the location of the Neptune Atoll Tracking Station misspells the word 'southwest' as 'soutwest'.
After the aircraft stopped on the makeshift runway, glasses and food were shown on a flat surface still there and intact. The landing roll was very bumpy as expected, also all the passengers were violently thrown around.
The aircraft was clearly showing that it was in a flapless configuration during short final to the makeshift airfield. This would never be the choice of a skilled pilot, unless there was a failure in the flap's lowering system. The only technical issue with the aircraft was shortage of fuel.
During the descent into the makeshift airfield, the pilot lowers the landing gear thereby increasing the drag considerably At this stage he was conserving fuel, as the aircraft was very fuel critical.
At time 1:17:29 in the film the navigation lights were on the incorrect side, when shown from the outside front view. Green was on the left (port) and red was on the right (starboard).
When the flight crew boards the aircraft, a Boeing 747, they walk right past the steps going upstairs and continue straight to the nose of the aircraft. The access to the flight station is on the second level. The only thing in the nose of the aircraft on the passenger level is passenger seats. There is no access to the flight station there.
When Major Masters is coming in for a crash landing, he first hits a high voltage tower and shreds it with his right wing. Instead of the aircraft slewing to the right from impact, it continues on straight with no damage to the right wing. He then crash lands on a highway and slides wheels up down the highway, his right wing neatly cutting off wooden telephone poles. Again, he continues straight, not slewing right and when the plane comes to a stop by the fuel truck, there is no damage to the right wing.
At takeoff, the Captain advances the throttles, two of them. There are four engines on a Boeing 747. The aircraft they show taking off is either a Boeing 757 or 767 a twin engine jet, but the aircraft they show in the air is a Boeing 747, a 4 engine jet.
When the terrorists shoots the hole in the side of the aircraft, the Captain notes a loss of fuel and the hole shows a liquid coming out. The fuel lines do not extend that far forward or aft of the wing. All the fuel lines are located in the wing box fuel tank area, where the wings connect to the fuselage.
The limo driver never tries the emergency brake.
