Factual error: Although it's already been mentioned that the scene of the shuttle being stolen from the back of the 747 is impossible because the shuttle wouldn't be fueled while being transported, it should also be noted that even if the shuttle was fueled, it would still be just as impossible. During the getaway, the thieves ignited the shuttle's three main engines to get free of the 747 and escape. The thing is, the shuttle's main engines are fueled entirely by the large external tank the shuttle and the solid fuel boosters are attached to during liftoff, and once the tank is jettisoned, these engines cannot be used. The only engines the shuttle's internal fuel feeds are the reaction control thrusters and the Orbital Maneuvering System (which are the two smaller engines located in the bulges just above the main engines). Both the RCS thrusters and OMS engines are almost totally useless within the atmosphere, so even if the thieves managed to get the shuttle free of the 747, they could only get it as far as it would glide unpowered. In fact, they could probably get it further if it wasn't fueled. It should be noted that this is not a fictional, futuristic spacecraft. It's a bog standard shuttle, stolen from NASA, on the back of the modified 747 used by them to transport the orbiter from its landing site to Cape Canaveral.
Factual error: The space station rotates for pseudo-gravity, but everyone falls along the rotational axis towards the bottom of the screen instead of falling outward from the axis as they actually would. Admittedly, this would be difficult to film (Stanley Kubrick's astronaut jogging in a giant hamster-wheel in Space Odyssey - nuff respect), so I guess they just hoped the audience wouldn't know the difference. (01:29:40)
Factual error: Two pilot/astronauts steal a space shuttle by firing it up and launching it off the back of the Boeing 747 transporter. This cannot happen: the 747 can't lift the shuttle with a full fuel load – it only just lifts it empty. It is not a fictional, futuristic spacecraft. It's a bog standard shuttle, stolen from NASA, on the back of the modified 747 used by them to transport the orbiter from its landing site to Cape Canaveral. (Why would they carry a fully fuelled shuttle anyway?)
Factual error: When a real shuttle is launched (or any other large rocket), the exhaust must be deflected sideways and guided through massive tunnels or trenches so that it does not bounce back into the base of the vehicle and destroy it. The Moonrakers lift off from inside an enclosed structure with no means of guiding the massive exhaust plume safely away. The tiny tunnel through which Bond and Holly escape would have been utterly useless to vent the exhaust of a real shuttle. In common with other movies, the noise and violence of a real launch simply cannot be portrayed accurately.
Visible crew/equipment: In the scene where the space station explodes, the wire holding up the model is visible when the explosion backlights it.
Continuity mistake: In the scene where Bond is in the helicopter being flown from the airport to Drax's estate, both landscape and weather change drastically from one moment to another as he approaches the castle. When the castle is first seen from the air in a long shot, it is surrounded by mountains and the sky is entirely clear. In the shots closer to the castle and from ground level, the mountains have disappeared and there are clouds in the sky. The cloud cover changes as well just after landing.
Continuity mistake: The space shuttles in this film, as with the ones in real life, can be entered or exited using the side front airlock. But one of the shuttles is shown docking with the docking port attaching to the right of the airlock. This would make it impossible to use the airlock. Later close-up shots of the docked shuttles, however, show the docking port properly over the airlock.
Continuity mistake: In the final scene, in the live transmission from the shuttle, there is a full shot of Bond and Holly who are covered by a sheet, and they are at least 4 meters from the camera. In the next shot Bond's face is right in the camera, and he can reach over and turn it off.
