I don't recall ever seeing this case discussed on here, happened quite a long time ago, 1943 I believe. The story of the blimp that crashed into San Francisco I think it was, and the two men on board vanished and were never found.

What do you all think happened?

One of the men got out to mark where they reported to have seen an oil slick and slipped and when the other came to assist, they both fell to their deaths.

Who knows for sure -- guessing it was one guy slipped and the other tried to help him and they both fell? Maybe they got in a fight and tumbled out?

I doubt it was a double suicide, but it wasn't aliens.
