I just found out this weekend, I know of 2 people who were on Flight 93.
One I knew of a few years back. Actually the daughter of a construction colleague.
Saturdays revelation was that an ex-wife of a business adviser was also on that plane.
I thought the odds of that being extremely odd, I thought "with 400 people on that flight what are the odds that I am connected in some small way to 2 of them".
But there were only 37 passengers on that flight, it was very lightly occupied that day.

That's some weird kind of coincidence. Feels like an episode of Lost.
