One of several 1970s documentaries on the subject of unidentified flying objects (UFO), supporting the view that Earth is visited regularly by extra-terrestrial engines and aliens.

Did you people see the same film I saw?

A movie that not only functions as a solid scarefest but a razor-sharp satire.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
