>I think any civilization capable of capturing and analyzing this 1970s tech would find it pretty trivial. Maybe, maybe not. You're making a lot of assumptions. Spacefaring aliens might have very primitive technologies in some sectors. Earth could be invaded, for instance, by spacefaring aliens with weapons technology similar to that from sailing ships of the 1700s (gunpowder-fired cannons): the key to FTL travel might have been a relatively simple part of physics we just somehow overlooked. Aliens might have spacecraft tech that looks like the Apollo technology.
