And what do you mean 'bad science' in Moonraker? You mean Marines don't launch into battle out of the back of a space shuttle armed with laser cannons? And we all know that artificial gravity is perfectly easy to generate by simply spinning your radar-invisible space station.
LOL! And shuttles are always carried on the back of the 747 fully fueled (no need even for the external tank!), guys who dress like East End London thugs can pilot one, they can lift off from an enclosed location without destroying it with heat or vibration, and the theme to CE3K will open any keycode doorlock.
It always amazed me that they ignored that fact that even a ‘radar invisible’ space station 300 feet in diameter is going to cause quite a stir on the surface when it’s spotted by the human eye.
