Mysteries Resolved

I was just thinking... the John Titor story is one example of a mystery which has been more or less, "resolved". That's not meant as a sleight to those who still believe in John Titor's story because you're welcome to believe what you like. But, even ATS has made an official stance on John Titor... that his story of time travel is a hoax.

So a question... are there other mysteries or conspiracies that have reached what you would call a "resolved" or "solved" status? What other mysteries and conspiracies has ATS taken a firm stance on?

The Moon Hoax Theory?

Any others?

It would be great to see them all in a single thread.
