Factual error: In the pre-credit sequence with Bond and Blofeld, the helicopter makes a steep dive. However, the sound it makes is for a fixed-wing airplane, similar to dive bombers in WW2. Helicopters make no such sound.
Factual error: It is impossible to fly a helicopter with both hands on the stick.
Factual error: There's no way Kristatos' thug in the diving hardsuit could have the maneuverability to get inside the wreck and move around in such close quarters. Diving hardsuits aren't made for shipwreck diving.
Factual error: One submission stated that when the Cuban hitman is killed with the arrow from Melina's crossbow, it goes in his back when it should have gone in his side. The corrector stated that we have no idea what angle she was firing from. Well, it is clear that she was standing at the left side of the pool (since we get a point of view shot from her) when he's about to dive in, and she shoots from there. She couldn't have got behind him that fast. So there is no way she could have got him squarely in the back.
Factual error: When Bond kills the guard who is trying to dislodge his pitons, the length that he fell would've left nothing but a big bloody mess. All he has is what looks like a few cuts and bruises.
Factual error: The machine gun set up on the motorbike wouldn't work. The bullets wouldn't be able to be fired out of the indicator lights as the lights are too small and there is no firing mechanism fitted to them.
Factual error: After Bond and Melina's car flies over an olive field, the Spanish villagers cry out in Italian. This is due because it was shot in the Greek island of Corfu, which has strong Italian bonds and culture.
Chosen answer: Whether he talked to her or not, Bibi would have inside information simply by being around him so much. She would have overheard things that a background check wouldn't reveal, like planned criminal activity.
