When I was kid saw a movie about a spaceship found on earth containing two dead astronauts. Can only remember parts and my guess is that MAYBE is from the second half of the 70's:
- The dead astronauts were humanoid, in fact -and oddly- human but they didn't have appendix.
- Their eyes were covered by some sort of white? plastic contact lens, the scientist said that maybe was for high speed protection while travelling in space.
- In the spaceship they had recordings with strange characters (sort of Japanese or something)
- The astronauts died when some vessel broke and released poisonous gas (I think).
Thanks a million in advance.
