During the fight scene in the Ambulance, Bond and the "doctor" exchange punches. Bond is up against the wall, and the doctor throws two punches that completely miss, however, it plays sounds as if both punches connected.
In the Bond movies, Bond goes through the utmost determination to keep his "007" codename a secret. Therefore it makes no sense for him to carry around a camera that has "007" printed on it, because if ever compromised, this basically gives away his identity.
After watching the demonstration of explosive bolas in the Brazilian monastery, Q tells his assistant to "have that ready for army day".
Although the USA had such an armed forces day since 1950, there was no army day in Britain until 2006.
The helicopter that takes Bond from Los Angeles International Airport to Drax's estate has a registration number visible on the bottom (belly of the aircraft) when it departs the airport, but not when it lands at the Drax estate.
After Bond is imprisoned with Dr. Goodhead, the ceiling begins to slide open and we can see that they are actually underneath the launching pad of one of the shuttles. The jet thrusters of the shuttle are above the level of the opening but when Drax appears beside the shuttle, the thrusters are now below the level of the opening. A minute later, as the shuttle prepares for liftoff, the thrusters are back above the opening.
Moments before Dr. Goodhead jumped with Bond out of the cable car structure in Pão de Açúcar she is wearing high heel, opened toe shoes. When she jumps and reaches the ground her shoes are flat and closed toe. It is visible that the scene is performed by a stunt using a wig.
When Bond and Jaws are fighting on the cable cars, Jaws falls through the sunroof. Bond and Goodhead slam the sunroof shut. It then cuts to a camera shot of Jaws from above, where the sunroof is obviously open.
When Bond and Goodhead escape through the ventilation shaft, the flame discharge from the Moonraker taking off "follows" them through the corridor. It cuts back to a shot of the Moonraker taking off, and you can see the flames are barely wide enough to touch the inner walls, let alone to follow Bond and Goodhead through the shaft.
When the first four Moonrakers take off, they do so in quick succession. Before the fifth takes off, there is just enough time for Drax to consign Bond to his fate and then board it, but before the sixth, Bond and Goodhead can escape, hide, jump the crew, get into their uniforms and still make it to the shuttle in time.
Bond looks the Drax airplane in Rio. A few seconds later, he see Dr. Goodhead.
She has both hands on the telescope. When Bond puts his left hand on hers, suddenly she has only her right hand on the telescope.
During the gondola/speedboat chase in Venice, a boat named "Elvira" with the registration "VE 7352" gets hit by a wave from the bad guy's speedboat. The same boat is seen parked at a different location in the previous scene, when the speedboat destroys another gondola at an intersection.
When Bond, Q, and M are discussing the rare orchid the map of Brazil shows central Brazil. However, when Bond is shown on the river being chased by the bad guys, his boat ends up going over Foz do Iguaçu. These falls are in southern Brazil, which is about 1000 miles from where Bond is supposed to be.
It is stated that the space station is not visible from Earth because it is using radar jamming. First, radar jamming consists of broadcasting interference, which makes the presence of the jammer known. Second, an object 200 meters across in low Earth would be visible to the naked eye - as the current smaller space station is.
In the opening sequence, James Bond, Jaws, and the pilot free fall for nearly two minutes. For that amount of free fall time, the jump would have to be made at or above above 25,000 feet, which would require oxygen equipment.
Jaws bites through the rope wire of the cable car. But when we see the winding wheel a second time, the rope is complete. In actual fact, it would take exerted pressure well in excess of 2,000 psi to snap a steel cable. Furthermore, if Jaws had severed the cable, it would have unwound with great force (and damage), and the cars would no longer be able to operate.
After launching from Drax's factory, the shuttles are shown in a proper inverted position, but with the cargo doors closed. When in orbit, the shuttle's main cargo bay doors must remain open to dissipate heat.
The pods of the space station are shown at all angles to the axis, but rotationally produced "gravity" is always away from the axis. Also, gravity would not change instantaneously when going from one corridor to another.
After discovering the orbiting space station, the Air Force immediately launches a space shuttle to investigate, which is impossible at such a short notice. Orbital missions have to be planned two years in advance, just to avoid collision with orbiting debris.
Laser beams travel at the speed of light (186,000 miles per second), so it will not appear to travel as a bolt or pulse of light. Instead, it would instantaneously connect the gun and the target. Also all laser beams are invisible in vacuum since they need something to diffuse on to be visible.
The blast from Moonraker 5 above where Bond and Dr. Goodhead are imprisoned is very light compared to the actual blast from a space shuttle on liftoff shoots flaming exhaust for hundreds of feet and much denser than the mere puffs of fire that are shown.
At Pão de Açúcar, Bond and Goodhead could not possibly have survived the fall from the cable car wire without serious injury, as the wire was significantly higher than the cable car; that height, plus the height of the cable car, plus an additional space would have been needed for the cable car to clear the very ground onto which 007 and Dr. Goodhead had fallen. Otherwise, the cable car would have been impeded by that same ground.
The external fuel tank on Moonraker 6, the ship that Bond and Goodhead had commandeered, falls away into outer space, and not towards earth as it should. Also it disappears very quickly, as if pulled away.
When Drax's astronauts are being discharged from the spaceship in large numbers, they seem to pass freely from inside the space station to outer space, without having to go through an airlock chamber or similar.
When the Moonraker is atop the transport plane, it has no Tail Cone. The omission of a such a vital piece of equipment would have disrupted airflow across the vertical stabilizer, rendering the aircraft unflyable.
In the opening sequence in which the shuttle is stolen, the shuttle's three main engines fire to break free of its 747 transport. This is impossible; the shuttle's main engines require the fuel provided by the large center tank that is attached only at launch time, so when being transported, it has no fuel. In fact, for aerodynamic stability, a special cowling often covers the engine bells during 747 transport.
When the last Moonraker shuttle launches, the counter reads "T-" (T minus), however, it incorrectly counts forwards instead of backwards. (The timers for all the other Moonraker shuttles counted backwards.)
When Drax' thugs "hijack" the shuttle, they are seen flipping a variety of switches and controlling various systems to "fly" the shuttle away. The shuttle's electrical power is provided by on-board fuel cells that operate only just before launch, thus it has no electrical power when piggybacked on its 747 transport.
Bond and Goodhead escape the fire and exhaust thrust from the Moonraker 5 blastoff by crawling through a vent duct that shortly ends in the control room. If there ever was an underground rocket launching complex it is extremely unlikely any vents from the launch bay would lead inside the complex itself, as the powerful thrust from a shuttle launch would no doubt shoot the flames straight through any vent and incinerate the room it ended at. Vents would most likely all be directed outside.
There are no Mayan pyramids in the Amazon rain forest nor near the Foz De Iguacu where Bond is located, however, the one that Bond enters is a fake, an entrance to Drax's Moonraker launch station, presumably constructed there by Drax's operation.
The announcement at the airport in London calls "BA flight 128 to Rio de Janeiro", but the Concorde, when it lands and passengers disembark, is an Air France plane. These are two different flights - the first Jaws' and the second being Bond's. Obviously they could not have been on the same plane or they would have seen each other, eliminating the surprise appearances later.
Many military nerve gases are designed to be absorbed by the skin as well as by breathing them, specifically to make a mere gas mask useless. As Q could not have known what other toxins were in the laboratory, they would have put Bond, the Minister and M in full length protective suits not just gas masks.
When Bond and Chang are fighting in the glass museum, there is a vase that is attached to a weight displacement pad that sets an alarm off. When Chang smashes the vase in half, that would also reduce its weight by half, yet, the alarm does not go off.
Bond is shown not wearing his wrist-gun for the last third of the film, but the gun reappears when he needs it at the very end of the film. During the Amazon speedboat chase, the hang glider ride, and the underwater python battle, his sleeves are rolled up and the dart gun is absent. When he is escorted inside Drax' underground lair, his right sleeve is suddenly rolled down. It is possible that he was carrying it around in a pocket and put it on when he put his spacesuit on, but more likely, they wanted Bond's sleeves rolled up while he was in Brazil but didn't want the bulky wrist-gun showing.
When Bond is free-falling, you can see the outline of his hidden parachute bulging out beneath his jacket. Also, the back side of his jacket is obviously pinned somehow to hide the parachute, otherwise it would be flapping all over the place from the wind. The same thing applies for the henchman, after Bond steals his parachute.
The contortion of Bond's face does not match the direction of real acceleration on a centrifuge. The effect of acceleration is actually felt down the length of the arm, not in the direction of circular travel. In actuality, he would have felt the force out the end of the arm, or toward the door of the pod.
During the speedboat chase scene, as Bond is being pursued by Jaws, we see a wide shot of Bond's boat approaching a treacherous waterfall. The way the shot is set up, Bond's boat is speeding toward the camera while the falls are in the foreground. The waterfall is an obvious matte painting. Take a look at the flow of the river in comparison with the falls. The river is clearly flowing freely from right to left, right up to the point where the waterfall begins. We can see that the waterfall is a powerful one which means that the flow of the river should be following it as the falls suck it downward, but that isn't the case.
During the gondola hovercraft scene through St. Mark's Square, the fringe at the bottom of the gondola hangs freely as if the vehicle is actually on wheels, rather than being blown around due to the cushion of air.
Under Moonraker 5, the time on Bond's watch leaps from 10:08:21 to 10:08:42 in a matter of seconds. This is because the latter time is actually a still mock-up of the display, printed onto the prop Seiko for narrative purposes.
When Bond is in M's office, he tests his wrist-gun. The dart becomes lodged in M's painting on the wall. Bond is not actually facing the painting and therefore the trajectory of the dart does not line up with it.
When Goodhead asks Bond about the lethal toxin-carrying satellites on board the space station, he says not to worry as they will be destroyed when the space station breaks up. At that point, however, with zero knowledge of the station's design, Bond has no reason to expect this whatsoever. The first explosion and failure of the superstructure indeed happens a split second AFTER Bond's reply.
When Bond is 'pulled' into the water by the snake, it cuts very rapidly between several shots. In some of the shots, it appears the snake is not struggling with Bond at all, and he can leave the water freely at any time. In other shots, the snake appears to be dead before Bond actually kills it.
