Factual error: In the scene where Kananga's henchman Adam is being interrogated by Sheriff Pepper by his car at the riverside, the boat chase arrives and two boats jump clearly over head disillusioning Sheriff Pepper and allowing Adam to make a quick getaway. However, as Adam is getting away in his car, screeches can be heard coming from the tyres, but they are on a dry dirt road.
Plot hole: James Bond shouldn't have gotten away at the end of the airport scene where he steals an airplane and pretends to be a flying instructor. He had no wings with which to fly away and he ended back up right outside the airport, so the henchmen, who seemed to still be chasing him one shot before he parked, should have been right on him waiting when he got out of the plane.
Factual error: The henchman with the prosthetic arm bends Bond's gun. It would require something in the range of 1000 pounds of pressure to bend a gun like that. It would be impossible for anyone to generate that much pressure since the arm is driven only by human muscle.
Visible crew/equipment: Four patrol cars are chasing Bond and the villain by the road. Bond and the villain arrive at a dead end and they jump over the road with their boats. The four vehicles collide just after. Look carefully and you will see that the right-seat passenger of the red car and the driver of the blue one wear a yellow protective helmet. (01:32:45)
Other mistake: When Bond gets his Rolex he explains that by pulling out this button it turns it into a hyper intensified magnet, but he actually turns the bezel to activate it. Also, Bond repeats Q's claim that it can deflect the path of a bullet. Lead bullets, even with copper jackets, are not affected by magnetism.
