The National Institute of Standards and Technology (NIST) started its investigation on August 21, 2002. When their 10,000-page-long report came out three years later, the spokesman said there was no evidence to suggest a controlled demolition. But Steven E. Jones also says that molten metal found underground weeks later is proof that jet fuel couldn’t have been all that was responsible. I visited the site about three weeks after 9/11, with Governor Pataki and my wife, Terry. It didn’t mean anything to me at the time, but they had to suspend digging that day because they were running into heat pockets of huge temperatures. These fires kept burning for more than three months, the longest-burning structure blaze ever. And this was all due to jet fuel?
