Not really my area but I've looked into this a bit because a few NDE researchers I follow got into a debate about institutional cover-ups more broadly and it bled into the Apollo stuff.
The thing that strikes me is - why would they need to scrub it quietly? If the original telemetry contained something genuinely anomalous you'd expect dozens of engineers and technicians to have seen it before any "scrubbing" could happen. These weren't small teams. Thousands of people had access to that data in various forms.
What I'd actually want to know is whether anyone has done a proper technical comparison between the reconstructed tapes from 2008 and any surviving copies held by third parties - universities, international space agencies, that sort of thing. Has anybody here actually dug into that rather than relying on secondhand claims?
The "they lost the tapes" story is genuinely odd I'll grant you that, but odd bureaucratic incompetence and deliberate scrubbing are two very different things. What specifically are people pointing to as the smoking gun here?
