I think they are. Heath Ledger sustained wounds from shards of the World Trade Center while he was walking near the buildings when they collapsed. He died because the asbestos from the building shards leaked into his bloodstream and gave him cancer. He kept the cancer from killing him with chemo for seven years but then he died =( I'm a personal friend of his mother and that's what she told me. R.I.P. good buddy.

this is new stuff i just heard:

in the original design of the world trade center, asbestos was supposed to be put around the steel corners and stuff, but the envriomentalists freaked because about the asbestos causing cancer (however, it would be behind SOOO much steel and building material) but it would just act as a fire retardant---what do u think about this??? EVEN W/O THIS I KNOW 9/11 WASN"T STAGED u crazy people who say bush is a neocon and responsible for 9.11 should go play in traffic
do u have a link about this asbestos thing--i dont want any theorist sites saying 9.11 was staged
