Jet engines? Sorry, after which crash retrieval program? I'd recommend a brief read of the history of jet engines, if you don't see it as a gradual evolution(as I have argued), rather than revolution.

It's quiet interesting, but doesn't leave a lot of room for alien influence. Haven't looked into ionic propulsion origins, but I assume it would be similar.

Ya, I just don't see why we would need alien help to discover this principle.
