Hangar 18 (1980)

An excellent science-fiction / conspiracy theory film if a bit crazy. A space shuttle mission goes wrong when a satellite the astronauts launch hits... something. That something being a UFO which lands in Arizona and is taken to a secret installation called Hanger 18. The President's man Gordon Cain (Robert Vaughn) doesn't want news of the discovery coming out so close to the election so everything is kept top secret, and for some reason the astronauts Steve (Gary Collins) and Lew (James Hampton) are blamed for the lost satellite and death of their colleague.

To be honest this seems a rather strange way to go about it, and as Steve and Lou understandably want to find out what is really going on they are soon leaving a trail of carnage and dead Feds across the US. Meanwhile at Hangar 18, the scientists are making some incredibly discoveries including about the origin of mankind...

A good fun film though somewhat marred by the bizarre actions of the US government and very inept way they go about it (though some might cynically say this makes the film authentic!) The investigation of the alien ship is excellent. The politics less so.
