In 2002, the astronaut was accused of being part of a conspiracy that supposedly faked the Moon landing.

In response, Aldrin, then aged 72, punched the conspiracy theorist.

The theorist is question is Bart Sibrel, and he does not believe that Neil Armstong, Buzz Aldrin of the United States landed on the moon in 1969.

A video of the incident has since resurfaced online, with many revelling in the assault.

During the exchange outside a hotel in Beverly Hills, Los Angeles, Sibrel can be heard saying:

You’re the one who said you walked on the moon when you didn’t. Calling the kettle black if I ever thought it. Saying that I misrepresented myself?

In reports from the area’s deputy District Attorney at the time Elizabeth Ratinoff, Sibrel had allegedly lured Aldrin there under the pretence of interviewing him.

As the pair shouted over one another – Aldrin can be heard saying ‘can you get away from me’ with Sibrel responding ‘You’re a coward and a liar’.
