Deliberate mistake: When the pilots are flying in the airplane there's a strange device above the co-pilots head. Later in the movie we see this same prop used again inside of the spaceship as the alien beauty Tanna opens up the hatch. (00:04:35 - 00:36:30)

Continuity mistake: The co-pilot radios in to Burbank tower in the middle of the night. In the next shot we see the saucer and it's broad daylight. (00:04:30)

Visible crew/equipment: At the funeral scene in the beginning of the movie, the wooden crosses added in the cemetery are obvious props. (00:03:40)
