Why does Rendlesham Forest still get official denial?

This has been bugging me for ages. The Rendlesham Forest incident in December 1980 is one of the most credible UFO sightings in British history - multiple military witnesses, radar confirmation, the whole thing documented in official records. And yet still the MoD's official line is basically 'nothing to see here, probably a lighthouse.'

A lighthouse. That's their explanation for multiple trained RAF personnel reporting a structured craft, landing indentations, and radiation readings. It's insulting to everyone's intelligence.

The question is: why? If it was genuinely nothing, why the defensive response? Why not a proper investigation and disclosure? There's clearly something the government doesn't want us to know, and Rendlesham is the case that proves official denial is standard procedure.

Has anyone looked into the documentation? The declassified files are online but they're heavily redacted. What's your theory on what actually happened there?

The 'lighthouse' explanation was genuinely ridiculous when they first released it. The witnesses were experienced military personnel, not random civilians. But here's the thing - governments will always deny UFO sightings because of the panic/economic implications. Imagine the stock market if everyone knew aliens were visiting Earth. Mass denial is policy.

I've read the declassified files multiple times. The redactions are interesting but not necessarily sinister - a lot of it is probably just classified for reasons unrelated to UFOs (military protocol, names of officers, etc). The lighthouse explanation is weak, sure, but that doesn't automatically mean aliens. Could've been experimental aircraft, a hoax, misidentification. We just don't have enough data.

Rendlesham is probably the best UK UFO case for legitimacy, but honestly the coverup might be more mundane than we think. Could be US military classified technology testing that they don't want declassified. That's not aliens, but it's still a legitimate reason for denial. Government secrecy doesn't always mean extraterrestrials.

What's never been properly addressed is the radiation readings. If those are accurate (and I have no reason to think the witnesses lied about them), then we're looking at either nuclear technology or something genuinely unknown. That's the data point the MoD really doesn't want examined.
