Audio problem: After the aeroplane crashed, a dinosaur stepped over it and the windows shattered making the typical sound of made-of-glass things when broken. I can tell everybody (I'm a pilot) it is not accurate because they are made of plexiglass (a sort of fibrous plastic).

Mistakes
In the scene where Dr. Grant gets rescued by the kid and they are sitting in the water tank (truck) eating candy bars they show the kid eating a "Crunch" bar with no wrapper, just in the tin foil. In the next shot you see him eating the same candy bar but the "Crunch" wrapper is now on, then in the third shot it cuts back to the kid and the wrapper is gone and you only see tin foil again.

Jurassic Park III mistakes
Factual error: Not so much of a mistake, but I want one of those satellite phones. I have a mobile which I can't hear in my pocket, let alone a hundred meters away in the belly of a dinosaur or later buried in a mound of dino dung. There is no way a 2001 phone's tiny speaker could penetrate that much insulation.
Visible crew/equipment: When the group was flying into the island, there's a shot of the plane flying in front of the cloud, and there's the obvious shadow of the helicopter that filmed that shot!
Jurassic Park III trivia
Dr. Grant's brown truck with the Museum of the Rockies and Montana State University logos on it is the actual vehicle that belongs to Dr. Jack Horner, paleontologist consultant on the Jurassic Park films as well as the man that the character of Grant is based on.

The scenes with the flying dinosaurs were supposed to be in the original movie, as it was part of the book Jurassic Park, but Spielberg decided not to include this in the first movie due to budget restraints.
