Yea, I was about to say that the name given for her husband does appear on
this list of 9/11 victims.
It's really not that hard to believe though. A lot of people died that day, and they all knew a lot of people so it's not surprising that on any given US domestic flight (particularly in the New York area), someone knew someone who died on 9/11. I'd bet someone on that Hudson River plane recently knew a 9/11 victim too.
