There are a lot of videos on youtube talking about underground tunnel wars as an explanation for the booms. I’m just keeping my mind open about it. The website I just posted is for the purpose of linking up times of events and sightings. When I think ‘unidentified flying object’ I really take into consideration that it is unidentified. It could very well be man made things we see in the sky. I looked at a lot of information after Rex’s youtube video and the most interesting thing was the UFO stalker website.
