The relevant experts are closer than you might think.
It's worth nothing that he passed, and that he was an avowed Moon landing denier. His death doesn't reinvigorate claims or evidence that were provably wrong when he first made them, and proven wrong between when he first made them and when they were captured for the program.
Then again it’s not clear that this muck is being dredged up again because Allen’s death is timely or because Artemis II is timely.
The claims are the same old long-debunked nonsense. As I wrote above, the demonstrative portions of the program were made in 2003. The rebuttals are the same as they have always been, but in this program many of them are demonstrated live on video which had previously never been done. (This was made pre-YouTube.) For example, the presenter shows that it's not impossible to take good photographs with the Apollo Hasselblads without a viewfinder by demonstrating it with an identical camera and lens and then showing the resulting photos. There were a lot of other demonstrations showing that what hoax claimants want to say about light and shadow are just factually wrong.
Similarly in 2008 Mythbusters finally did an episode on the Moon landing hoax, doing even more great demonstrations.
