The first Chinese astronaut has said he heard mysterious knocking sounds on his spacecraft and I believe it may have been an intelligent biological entity trying to establish contact with him. Sadly, he didn’t make a similar knocking noise to make this alien contact, but instead was both puzzled and worried at what it could be. But he knew, as you can hear in his own words below. He knew.

Another astronaut John Glenn, was interviewed and I have it in an old 1960s UFO magazine, but he saw fireflies…white glowing tiny insect size objects swarming around his module while in orbit. He banged on the metal sides and it sent the little buggers up swarming again around his windows. Here is also a video below about it that I found.

BBC News states: 
Imagine you’re alone in a tiny spacecraft – it’s your first time up there, all alone in endless space. Then suddenly – a knocking sound.

That’s what happened to Yang Liwei, China’s first man in space, on his maiden flight in 2003.
In a recent interview, he has now recalled hearing “someone knocking the body of the spaceship just as knocking an iron bucket with a wooden hammer”.

“It neither came from outside nor inside the spaceship.”

Naturally, he got a bit nervous and had a peek out the porthole but failed to spot any explanation for the eerie knock.

He’s not been able to figure out what it was, neither up in space nor after returning to earth. He has even tried – but failed – to recreate the sound so that experts could help him identify it.
Unsurprisingly, the story about unexplained mystery sounds in space has garnered quite a bit of attention.

What – or who – was knocking on Mr Yang’s spacecraft as he was all alone miles from the safety of the earth?
