Factual error: Bond tells Q at one point "I've lost my PPK." However, he has been carrying a Walther P-5 throughout the movie, and continues to use it in the later action sequences. A PPK never does make an appearance in the movie. The P-5 was also used that year by Bond in "Never Say Never Again").
Factual error: On the railroad when the knife-thrower is welding the jewel canister onto the circus equipment, there are bright flashes of light. Later however, the knife-thrower attacks Bond with a gas welder. Oxyacetylene torches (gas) merely heat the metal until it melts. They do not produce blinding flashes, unlike arc and MIG welding kits (electric).
Factual error: In some scenes, the Communist soldiers use the wrong armament: the Cubans use American M16s (whereas they should be using AK-47s), and Orlov's bodyguards (in the scene where the jewels are switched for the bomb) have Austrian Steyr AUGs. It would have been rather problematic for socialist countries (during the period of the film) to keep captured Western weapons constantly supplied with spare parts and ammunition.
Factual error: When riding in the truck with the Cuban soldiers Bond pulls their parachutes. In the next clip they are 5-6 meters up in the air. That is impossible. First, parachutes are not shot out, but merely pulled by the passing air. And the truck does not go fast enough to pull the parachutes. Second, even if the truck went fast enough, the soldiers would be pulled horizontally - and just fall off the truck, not get pulled vertically up in the air.

Factual error: Bond pulls his mini jet out of the path of the missile racing in from behind, making it narrowly miss his aircraft. Like most such piloting stunts from Hollywood, it wouldn't have worked. Modern anti-aircraft missiles have proximity fuses and fragmentation warheads or continuous-rod warheads. They actually deliberately pass by the aircraft they are trying to destroy and explode next to them, because the cross-section is greater that way. There have even been cases when a missile actually hitting an airplane just disintegrated without exploding, thus saving the target.
