I was taken to another star systm and returned, over 33 ago. I was debriefed by the goverment over this, and a certain ammount of secrecy prevails here.
However, it is not as much as an interesting topic as some may believe, on paper, for their science is not significantly more advanced now, on paper than ours. Also , even though the existance of these things is now established, they cannot really do anything for our planetary system. I do know that there is a good case to wheather balloon this area, but it now being in human collective conciousness, it would be a better idea to put a captured//crashed craft in the Transport Museum.
