Are you asking "How so?" about my phone or about USSR very likely sending a bunch of men up to their deaths and covering it up until the first guy managed to not die? Just in case it's about the USSR thing...
There were two Italian brothers who intercepted this broadcat https://www.youtube.com/watch?v=9Sgc1I9sjfc
of a female Russian astronaut who was apparently in a crashed space craft. Apparently, there have been others. There have been other weird stuff involved in the USSR space program (Russians citizens claiming to have seen crashes or debris, a lot of "meteors" in Russia around the time, etc.. There is no official statement from Russia for obvious reasons, but this is something a lot of people believed to be true or, as others have said here, believable.
