While browsing Wikipedia's article on the history of the space race between the United States and the former Soviet Union, I came across the conspiracy theory talking about possible cosmonauts before Yuri Gagarin who may have gone into space but failed and ended up dead/missing. http://en.wikipedia.org/wiki/Yuri_Gagarin The conspiracy theory on wikipedia linked externally to http://www.lostcosmonauts.com/. It made a few claims, but it didn't really back it up with evidence. There were a few .ra sounds of recordings taken by the "Judica Cordiglia brothers." Surely someone else on Earth would have picked up transmissions like the ones the "Judica Cordiglia brothers" have. Later in the site, they also have a translation of a female cosmonauts' voice of a failed re-entry here: http://www.lostcosmonauts.com/tradeng.htm. It doesn't sound very authentic, especially the repeated "FORTYONE." The mission crew photos were also questionable... http://www.lostcosmonauts.com/erased.htm The site also at one point has a crackpot tone to it: While the conspiracy theory does present an interesting argument, there are a few things I don't understand. The Soviet Union collapsed a while ago, so why hasn't this information, if it is true, released like the other aspects of the Soviet space program? The site listed above mentions "for reasons unknown" but I find it rather suspect, and says that their information is completely true :uhh: . Since it is known that we mustn't trust everything we see on internet, I can't trust this site as a reliable source of information. It is an interesting thought though, is it possible that the former Soviet Union might have sent up cosmonauts before Gagarin? Is there a reliable source for any indications or claims made to substantiate the (somewhat suspicious) rantings of "The Lost Cosmonauts" website? Or is this just another conspiracy theory that doesn't really amount to anything?
