Just something I was curious about before I go back to work, I've been watching quite a few documentaries ( though some of them are pretty bloody ballsy calling themselves such ) on the topic and would love to get some input from the lovely folks around here!
I find several cases quite compelling and they certainly raise some questions. I draw your gaze to a case in Australia in the 60's at a school near Melbourne.http://en.wikipedia.org/wiki/Westall_UFO#Unofficial_investigation
The quintessential UFO case is also worth the read; http://en.wikipedia.org/wiki/Roswell_ufo
I found it interesting the USAAF released a statement that said they had a flying disc, then took it back the next day. Even children know, no takesy backsies. . .
I also found Rendlesham Forest to be rather interesting. I was amused that he took photos, sent them to the base lab and the photo lab said that none of them came out and then refused to give him the negatives back. http://en.wikipedia.org/wiki/Rendlesham_Forest_incident
It's very possible many of these are simply black projects, natural phenomenon or easily explainable occurrences under unusual circumstances. However, there are a few there can make one generally think. The biggest problem I've had is finding information that isn't biased one way or the other. It's something that people gravitate to one extreme or the other where I tend to find myself in the middle. . . I don't think we are alone in the universe, it is after all infinite, but I don't know if all the worlds governments are going so far as building alliances and trading technology behind the general public's back. . .
