My Dad used to listen to Art Bell on the radio until the wee hours. I always thought it was bs, the things discussed there, but some of it is compelling.
Hangar 18 for instance. My Dad was in the Signal Corps during WWII. Evidently during the war he heard information much like what what Art Bell talks about. Concerning the Roswell thing, one of his friends, an Air Force Colonel told him that there was indeed something secret moved from Nevada to Ohio (Wright-Patterson?) He saw it and told my Dad...it was brought in on a semi truck and looked like a saucer with a cover over it.
During that time, there was a UFO sighting about 50 miles north of Mobile (Brookley Field.) Dad and an Army Major drove a command car up to a farmer's field to look at it. The Major was trying to freak out my father by telling scary stories during the drive.
Well, they got there and it turned out to be a weather balloon. But it was an official drive in the country. Dad said those guys could BS like you wouldn't believe.
