Today, a debate about 9/11. Ever since the attacks took place, many people across the country have raised a number of questions about what actually happened on that day in New York, Washington and Pennsylvania. Websites, articles, books and documentaries have put forward a variety of alternate theories to the government's account of what happened.
The most popular of these is a documentary called "Loose Change." The 80-minute film first appeared on the web in April 2005. Since then, it has had at least 10 million viewings and is described by Vanity Fair as "the first Internet blockbuster." As the popularity of "Loose Change" has soared, a book dealing with the questions it and others have raised about 9/11 has been published. It's called "Debunking 9/11 Myths: Why Conspiracy Theories Can't Stand Up to the Facts" put together by the editors of the magazine, Popular Mechanics.
