And of course, if the Roswell event was aliens-crashed-to-earth-in-a-space-ship, then we certainly need to know about that! Or at least get as close as we can to that particular truth.
Some might argue that, if Roswell was strictly a war related event, that national security demands such secrecy, and we shouldn't be delving into areas that might make us vulnerable to others. That's disingenuous or naive, depending on which reason is believed by those who utter such denials.
So thank you to all the Roswell investigators out there (and I mean real UFO researchers, not the, you know, skeptoids of the realm) who still go at it in terms of uncovering what really went on at Roswell, New Mexico, in 1947.
