anons, reading 9/11 docs, since this is a lawsuit, they are subrogating the loss of monies.. meaning trying to get people who are responsible to pay for the monies paid out for the damage..
In car insurance.. you go borrow a car and get into a wreck with it. The car's insurance first pays, then that company subrogates and comes after your company to pay for what was originally paid. So the damage was paid out, then the company that covered the initial payout, goes after the responsible parites.
That is what this is.
United Airlines is implicated so far. Who owned American Airlines during 9/11 and did that change?
