In a recent interview with the local media, China’s first-ever astronaut Yang Liwei has revealed he heard a peculiar knock on his ship during his first trip into space.
This incident occurred in 2003 and he recently revealed that the knock felt like “someone knocking the body of the spaceship just as knocking an iron bucket with a wooden hammer,” BBC reported.
The 51-year-old’s unexplained experience has raised all kinds of theories – including aliens trying to enter his ship.
He admits he hasn’t heard the sound again since returning to Earth.
In 2003, he became the first person sent into space by the Chinese space programme.
He eventually orbited the Earth several times during his historic 21-hour flight.
He recalled his out-of-this-world experience in a recent interview with Chinese media.
He said: “A non-causal situation I have met in space is a knock that appeared from time to time.
“It neither came from outside nor inside the spaceship, but sounded like someone is knocking the body of the spaceship just as knocking an iron bucket with a wooden hammer.”
Mr Yang revealed he was very nervous when he heard the sounds and moved close to the spaceship’s porthole to investigate.
But he could see nothing out of the ordinary.
When he returned to Earth he explained the noises to officials with the space programme and tried to imitate it with instruments.
The sound has also been heard by other Chinese astronauts.
Yang Liwei said: “Before entering space I have told them the sound is a normal phenomenon, so there is no need to worry.”
