Cause Of Yuri Gagarin Death Finally Revealed By Fellow Cosmonaut:  This is probably only of interest to space and history nuts like myself but the Russians recently allowed the truth about the crash that caused the death of Yuri Gagarin to be released.  In contrast to many of the UFO and other conspiracy theories floating around it seems that Gagarin's aircraft was rendered unstable by the nearby supersonic passage of an SU-15 being tested, which was flown in violation of it's flight plan.  I think it is amazing that it took the Russians 45 years to finally set the record straight.  Never underestimate the Russian penchant for keeping things secret just because.
