The "Apollo Detectives" channel is absolutely chock full of absolute garbage, and as anyone posting anything remotely critical is banned in short order, and/or their comments deleted, it seems a shame that their utter stupidity goes unchallenged (the excellent work of their nemesis Phase52012 aside
https://www.youtube.com/@Phase52012).
I thought it was time critique of their failings was made here, as it's bound to get back to them and annoy them a lot.
Their latest vomitus
contains many ridiculous claims, but the first one is that this image:
https://www.flickr.com/photos/projectapolloarchive/21063236643/in/album-72157658983462236Contains a defect. They have decided, because ChatGPT said so and as we all know AI can never be wrong about anything, that it shows a hole in the backdrop that NASA were somehow incapable of realising was there.
That "hole" doesn't appear in the photos either side of AS17-140-2149.
When I looked at the flickr view of that photo, it looked different to the one they were showing, so I had a more careful look. As you can see the two defects are different sizes and overall shape:


They do, however, share common feature - like the loop across the top and centre. the long filament on the left hand side, and the overall shape of the right hand side (and another long filament). Two different backdrops, or maybe a piece of detritus whose shape has been altered by different scanning processes? Which do we think is more likely?
The LM is visible in that photo, and Marcus says: "isn't that amazing nobody's pointed that out".
Well, this edition of Aviation week and Space technology from January 1973 certainly pointed it out:

The other claim they make regards Apollo 12 photographs of the ALSEP offload from the SEQ bay (AS12-46-6783 onwards).
https://www.flickr.com/photos/projectapolloarchive/21077369024/in/album-72157659081038325Their claim is that in photos taken after the offload, the SEQ bay door is taped shut, and that this is impossible because it would be too high for the astronauts.
What they don't seem to understand is that the main SEQ bay door was raised, and lowered, by pulling a lanyard - it can be seen in diagrams here:
https://www.ninfinger.org/karld/My%20Space%20Museum/lmdiags.htmand in video here
The door itself is hinged, and you can see that on raising the door, more of the lower half is revealed (the tape inside the green box)

(The red circles highlight studs that can be seen on the door when it's lowered).
So no, the scene wasn't "reset" to take the photos after the offload, they just closed the door by the simple mechanism of pulling on a rope. The tape you think is sealing the door is just holding the Mylar in place on the panel.
Feel free to add any other easily debunked stupidity (this could be a long thread!).
