Factual error: When Goldfinger's pilots fly over Fort Knox to deliver the sleeping gas, they could not have done this in real life because Fort Knox is in a no fly zone. Fort Knox's airspace is a 3.5-mile radius and it goes up to 3,500 feet. They'd have been intercepted in no time. (01:29:06)
Other mistake: When Q briefs Bond about the Aston Martin, he tells him the homer (tracker) has a range of 150 miles. When Bond is tracking Goldfinger in Switzerland, he is momentarily distracted while Tilly overtakes him. The blip on the screen has then disappeared, meaning G's car is some 150 miles ahead. But moments later, Bond pulls up on the hillside above where G has stopped for refreshments. How could he have made up the best part of 150 miles in so short a time?
Other mistake: Inside the plane Bond punches Goldfinger's chest. However, Goldfinger reacts as if he had been punched in the face.
Plot hole: As Goldfinger points out there are 41,000 troops stationed at Fort Knox so how in the world was Goldfinger able to make his escape? The troops should have easily been able to overpower Goldfinger's men without much of a fight and certainly shouldn't have been so easy for Goldfinger himself to get away on the helicopter.
Continuity mistake: The wall separating the cockpit of Goldfinger's private plane seems to have disappeared when Mai Ling is waiting for Bond to lower the steps of the plane as she can be seen standing right behind Ms. Galore's seat.
Continuity mistake: The crane from the junkyard stops at the car's roof, but from a different angle it's up and being lowered again.
Continuity mistake: When Goldfinger shoots and breaks the plane window, chaos runs havoc: curtains flutter wildly and a strong wind hurling inside makes objects fly around. Yet right when Goldfinger is lifted up the air (an obvious chroma effect) the curtains and even Bond's hair stop moving. This happens between one frame and another, it has nothing to do with physics or pressure inside the plane.
Suggested correction: If we remember that the cabins of these types of jets are pressurized, the continuity makes sense. When the window is shot out, explosive decompression occurs with the higher pressure in the cabin causing violent gusts as it flows toward the hole in the window. As Goldfinger is lifted toward the window and blocks it with his body, the flow suddenly stops. By the time Goldfinger is sucked through the window, the pressure has equalized and the cabin, though drafty because of the open window, is near normal again. In reality, the pressure difference would not be enough to suck a corpulent man through a small window, but that's another issue.
The curtains stop fluttering before Goldfinger is sucked-out. They are fluttering yet a shot later they are still.
Factual error: A crushed Lincoln would be too heavy for a Ford Falcon Ranchero to haul. (01:22:05)
