Factual error: In the scene where the ninjas are attacking the volcano, they are armed with rocket guns. While the rocket guns, MBA Gyrojet Rocket Carbines, are real, their 13mm rocket cartridges could barely beat out a .45 ACP pistol cartridge in stopping power, not to mention they couldn't cause huge explosions like they did in the movie.
Factual error: In the beginning scene involving the U.S. spacecraft, as the front door on the unidentified ship starts to close around the U.S. capsule you can see the reflection of red light across the hull of the captor's ship. Where is this light coming from? It can't be from the sun, because sunlight only appears white to our eyes.
Factual error: At the dock where Bond and Aki are investigating the Ning-Po, there are cylinders labeled as containing turpentine made by Osato Chemical, but which Bond figures out are really filled with liquid oxygen (LOX), presumably to be incorporated with rocket fuel in SPECTRE's mischievous meddling with other nations' spacecraft. To keep the LOX inside cold and liquid, the container needs to slowly vent oxygen to carry away heat which is constantly entering from outside. This venting would be visible as a stream of water vapor exiting a port, such as what's commonly seen leaking from the sides of rockets which are waiting on their launch pads. There is no such venting, which means the LOX inside will no longer be LOX by the time it gets to where it's going.
Factual error: When Bond is hiding on the monorail cart, it stops at the astronauts' quarters. After Bond gets out of the cart, a second cart passes by, even though the cart he arrived in is still on the track (out of shot). No one moved the cart before the second cart passed through.
