I read an article today about recently discovered documents from the Apollo 10 mission. As they were circling around on the dark side of the moon, their radios picked up weird sounds/feedback and the origin of the noise could not be located.
I only clicked on the story because it was listed as Apollo Astronauts heard unexplained “music” on Dark Side of the Moon. I figured that, while they were in space, somebody brought along a copy of the album, played it, and they all commented about some piece of instrumentation on the album.
Turns out, it’s not about Pink Floyd at all, but the aforementioned feedback.
An attempt at explanation is posited in the 2nd half of the video snipped, below.
