Things I learned from watching this movie
1. When the plane is flying at the beginning its call letters are C-FJSM. But after it crashes at least three of the letters on the fuselage are now LHA.
2. The throttle controls in the single engine plane shown at the beginning are actually for a dual engine plane.
3. After the helicopter carrying the soldiers is shot down, Captain Steakley orders Haldeman to get the others out of the wreckage. When she goes into the wreckage she tells the survivors that this 'plane' is unstable and they need to get out. She should have said that the helicopter was unstable.
4. While the action is supposedly occurring in some Central or South American country, the call sign of the plane that crashes (C-FJSM) indicates that it is registered in Canada.
5. Somehow, even though Professor Roxton has been stranded in the dinosaur crater for ten years, his clothes show no wear and tear. Plus, he apparently found a vest during that time, that he was not wearing at the time of the crash.
