#OTD in 1930 American astronaut and aeronautical engineer Neil Armstrong was born.
In July 1969, Armstrong and Apollo 11 pilot Buzz Aldrin performed the first manned Moon landing. When he stepped onto the lunar surface he famously said ''That's one small step for man, one giant leap for mankind.''
I though it was “one small step for a man”. That seems to make more sense.
Which is correct?
Clarification at mod request: please don’t answer with what you think the audio sounds like, because that’s a matter of opinion. There is professional audio analysis to cite (although a good answer would evaluate the strength, or not, of that evidence) as well as Armstrong’s reports of what he intended to say and what he believed he said.
