The Lost Cosmonauts is devoted to the claims of a pair of Italian brothers who say they recorded, via a home-built studio built in the early Sixties, some transmissions of early Soviet launches. Some of these recordings are of previously unknown flights into space before that of Yuri Gagarin, the first known human in space.
They also have recordings they claim are of failed flights wherein the cosmonaut perished, flights never acknowledged by the notoriously secretive Soviets. They make for ghoulish listening.
Make of it what you will. I think it's a fascinating "what if" and "secret history" kind of site. You can also read some well-grounded debunking of the site's claims, just for balance.
