Ah thanks for clarification re life insurance. So the pilot wouldn't have had a reason to 'hide' his suicide, and he could've just crashed into the sea and got the same result. I don't believe it was suicide btw.
It just seems like most of the scenarios left are the more 'tin foil hat' ones, with cover ups and misinformation.
I'm not usually a conspiracy theorist, but something unprecedented has happened here, and I'm not sure when, or if, the truth will out.
