OK, this is in my field. I was under the impression that the World Trade Center didn't contain asbestos because the environmental concerns were too great when it was built. Mesothelioma is caused by asbestos exposure. Was there asbestos exposure in the aftermath of 9/11? Could she have been exposed to asbestos at any other time in her life? Mesothelioma usually does take a long time to develop. If it was a 9/11 exposure,then the terrorists have claimed another life.
Asbestos was used in tower 1 until about the 45th floor, as a heat retardant for the structural steel. It was discontinued after that. It wouldn't have made much difference if it had been used in the upper floors, because it would have been stripped off the structural steel by the impact of the airliners that hit the WTC. Morons sometimes score with a lucky shot, and 911 is proof of that.
Wrong- at least one of the towers contained asbestos insulation for a certain number of floors up. I remember a lot of discussion about how, if both buildings had had asbestos insulation completely, that they would have survived much longer. Environmental regs were applied during construction, leaving top floors protected less.
See the link in post 9. Ask freeper alice_in_bubbaland. She has info on that.
