Okay i'm bumping this up because i've finally got to see it all......Dont let the fact that this was made in 76 put you off. I think it's without doubt one of the best UFO docs i've ever seen....Air Force personell by the bucketfull telling like they think it is ....I would say they would be kept much quiter these days.
Hynek et al explaining that the "swamp gas" theories so often touted by the debunkers were taken out of context.
Jaques Vallee talking about cattle mutilations......Including eye witness cases from the 1800s

. Strange stuff going on with these mutilations.....wtf.
Look at the Spheres filmed in the 60 s ---------- Identical to the ones on the Jamie Maussen tape ---same configurations etc etc ----Often dismissed as Balloons ----This 60s film was subjected to hours of analysis and were deemed not to be balloons , kites etc.
This documentary gets the Bogey

and i think it's much better and more revealing than many of the modern Docs....also some great pics and footage in there.
A hidden Gem of a doc. Do yourself a favour and watch it.
