This fairly young guy likes to collect old media equipment and tapes and produced this video of his latest purchase:

Wow, what a find!

Not the "original" tapes that everyone was hoping for, but still amazing that something like this exists after 50+ years.

Oh, cool! I saw that video in my YouTube recommendations but hadn't watched it until now.

I'll have to send him my family's old home movies on Betamax.  ;D
It suddenly struck me that that tiny pea, pretty and blue, was the Earth.
I put up my thumb and shut one eye, and my thumb blotted out the planet Earth.
I didn't feel like a giant. I felt very, very small.

Aaand predictaby, the loons have latched on.

The blunder has found yet another (yawn) 'smoking gun', and in a facebook post claims that after Aldrin says he is about to 'partially close the hatch' (the word partially is important here), he hears a creak and a sound of a door 'lightly slamming'.



Not sure I've every 'lightly slammed' a door, but whatever.

He claims to hear the same muffled light slamming at the same point in CBS' footage:



but it's absent in the remastered and other NASA releases.

For my money, the two sounds are entirely different - would be interesting if anyone could compare the nature and timing of them more accurately.

"A-ha!!" He's saying, "the sound of Aldrin slamming the door has been scrubbed, because you couldn't have heard it through the spacesuit microphone".

Or (and here's a wild and crazy suggestion), it's a sound from the TV studio (where presenters were poised to interrupt with observations), or it's from a door opening in Mission Control. The various mission control loops available here https://apolloinrealtime.org/11/ also have no evidence of any kind of door opening & closing sound, or any sound at all.

The Apollo photos clearly show that the hatch wasn't shut completely, so wouldn't have made any sound as it closed, because it wasn't. Occam's razor? The sound is from the TV Studio making the broadcast. CBS & NBC had different noises in different places, and my suggestion is that it's from their studio microphones. The BBC's transmission has no noise at all:

It's so cute that he thinks an LM door can "slam."

I'd actually suggest that the sounds are possibly from when it was either cleaned up or the copy made. If you listen carefully, you can hear background conversations and even a bell rings (sounds like the bell you would find on a bike).

I did watch the intro to the video showing how he went about it, and there's a clear 'audio out' link into his PC (rather than it being mic'd up in the open).

I went to the trouble (because it's unlikely Jarrah will) of comparing the audio from the CBS and NBC footage:

Both clips are set to start at "partially close the hatch". The 'click' of a door closing is at around 4.6 seconds in the NBC footage. The completely different sound in CBS' footage is 4.0 seconds. Different sounds, different points in the audio. The peaks at the end of the CBS file are studio commentary, not Houston/Apollo. I wanted it to be absolutely clear that the two sounds are not at the same point in the audio.

There is no discrepancy in running time in the audio files, which you can see where where I've ended both clips after Aldrin says "Making sure" - they are milliseconds out, more down to my selection errors than anything.

The orange marker line in the NBC wave file is where the initial squeak occurs that Jarrah claims is the door closing.

Both files have studio commentary interfering with the feed from Apollo, clearly indicating an open mic picking up background noise in the studio.

I might see if I can increase the volume a lot and get clearer versions of the sounds, but I've already put more effort in than the Blunder has so I may not.
