Apollo 11 was the historic flight that first landed humans on the Moon. It became one of the biggest landmarks of the last century, showing the world that our technology was advancing enough to take off and reach towards the stars. And while Neil A. Armstrong and Edwin E. Aldrin Jr. made history by setting foot on our planet’s only moon, their pilot Michael Collins flew the Command Module Columbia alone in lunar orbit. The mission is, perhaps, best remembered by Armstrong’s words broadcast on television to a worldwide audience: “one small step for [a] man, one giant leap for mankind.”

However, there are many more things that the astronauts spoke about and, turns out, their exchanges were quite funny. While remembering the historic moment, most people probably think of how serious and monumental it was, but not many know what transcripts truly show. After all, it’s easy to forget that astronauts are also human and even they can be goofy sometimes.
