i was at the drive in with my husband ( he was my boyfriend at the time )& i looked up thru the windshield... it was cigar shaped, but had no propellers or 'wings' ( & it wasn't a copter) it had a single glowing red light on its belly. the red light was what I first noticed looking out from the windshield, then I was able to make out the shape ( it was dark at the drive in) it made NO noise, & at first it looked like it floated past us... & so many people started getting out of their cars or honking. it flew out past the screen, then it started moving up & down & sideways & was doing it too fast to be a blimp- then it just 'zoomed' out of sight.
btw the way the movie was Rocky 4 (1985)
