Bravo, SS for having the courage to speak up on this controversial subject.
Being naturally curious myself, I have been following the subject and engaging as time allows. There are several investigative teams out there which have been working in the trenches to uncover by their own means whatever secrets that are being withheld. One of my favorites is the team from "Unidentified: Inside America's UFO Investigation". Some of the very capable team members include Louis Elizando, Chris Mellon, Tom DeLongue, and last, but not least, Steve Justice.
The recent release of previously classified military videos shows, IMO, at least a certain willingness on the part of the government to come clean with us concerning what they do and do not know. I tend to believe it is but the tip of a much larger story. It would seem that the government is testing the waters so to speak before moving deeper with it.
Personally I take the willingness as a good sign. All revelations begin with the willingness of those who withhold them to finally release what they know.
I do understand the caution. If it turns out that the government has been lying for a long time, revelation will only shine a light back on the reasons for their reluctance to trust the public (if indeed this is the case -- it might not be). What those reasons could be I have no idea. Perhaps the story was too big and they feared an explosive public outcry upon it's release.
However, as far as I'm concerned, I just want to finally know. If my curiosity kills me, so be it.
There is another way to look at intergalactic travel, as our "enlightened" contingent here at IO might posit very quickly... Some don't need a spaceship to get way out there. Perhaps there is a means for unlimited and instantaneous travel outside of space and time. One would not be limited by the laws of physics in that case... there would be no physic to limit. (I am suffering from a bit of insomnia tonight and think I might have gone a bit too far myself in some ways).
