I always wanted to see Star Trek put out a UFO episode from pre-warp aliens' perspective. That is to say, have the main characters of the episode be aliens from a planet similar to 20th century Earth. Feature the series main characters as aliens, and tell the story entirely from the alien world's point of view. This would mean not showing the Enterprise unless the aliens visit the ship, and then only showing the ship from their point of view.
Do you think this could have worked? Was this done, and I simply missed the episode? I'm aware of DS9's Roswell episode, but not quite the same. That was from Quark's point of view, not 1947 Earth's point of view.
