I was flipping through, looking for something to watch & I came across this movie.I'm not normally into movies about outer space, UFO's & stuff like that but after seeing all the names that were in it, Gary Collins, Robert Vaughn, Joseph Campanella but most of all, Darren McGavin (Sorry if I forgot anybody else) I knew I had to check it out.Hangar 18 turned out to be pretty good (Kinda makes you wonder, what do they know that they don't want us to know? Know what I'm saying?) It was interesting to see the outside & inside of the ship, everybody trying to figure out how & what made it work, the 2 astronauts who were accused of causing the accident trying to clear their names & the officials doing everything they can to keep the UFO under wraps.The best part of the movie had to be the ending, the twist within a twist.I also read on IMDb that in 1983 Hangar 18 was released under the name Invasion Force which had an alternate ending.I wouldn't mind seeing the alternate ending but if I don't, no bother.Hangar 18 isn't a movie I'd buy but it is worth watching, if you're a fan of extraterrestrial movies or not
