I saw UFO from Apollo, says moon hero Aldrin
Buzz Aldrin, the second man to set foot on the moon, said he glimpsed an unidentified flying object during the Apollo 11 flight.
The astronaut also said the first humans to set foot on Mars should never return to Earth during a Reddit "ask me anything" question and answer session.
However, Aldrin (84) was reluctant to describe the sighting as an extraterrestrial craft, even though he does believe there are other life forms in space.
"I observed a light out the window that appeared to be moving alongside us," he said.
"There were many explanations of what that could be, other than another spacecraft from another country or another world – it was either the rocket we had separated from, or the four panels that moved away when we extracted the lander from the rocket and we were nose to nose with the two spacecraft.
"So in the close vicinity, moving away, were four panels. And I feel absolutely convinced that we were looking at the sun reflected off of one of these panels.
"Which one? I don't know. So technically, the definition could be 'unidentified','' he said.
His remarks triggered accusations of a cover-up from those who believe in UFOs. But he urged caution. "Extraordinary observations require extraordinary evidence," he added. (© Daily Telegraph, London)
