I always wondered what became of ol' BG....
I believe Col. Halt and the men that were with him, but Larry Warren seems like a poseur who is embellishing his experience (seeing aliens, changing his story) in order to sell books. This is all the more obnoxious given that this event deserves to be treated seriously.
RE: the lighthouse mentioned above: LOL! I don't think people who lived in close proximity to a lighthouse (civilian and military) for years would suddenly forget the lighthouse was there, or how it appeared to them. You can't pass off the Rendelsham events on a mistaken lighthouse.
