Interesting. I was recently watching a documentary about the collapse of the WTC on 9/11 and they were interviewing a couple of the engineers who studied the steel girders from the dump. They said that some of the fire retardant coating they found could be wiped off with your hand. Then there was this whole tangent about a Mafia mobster who had sold the fire retardant coating to the original builders. (The main one which was a Rockefeller…I had no idea.) He ended up in jail for fraud. DiBono, I think his name was.
