I downloaded this "Cutting Edge" documentary today, and it was about Tania Head
(Wiki), who claimed that she had survived the 9/11 attacks and was one of 14 people who were above or at the point of impact and survived.
She became the face/voice for all of the survivors of 9/11; however, she wasn't even in New York when it happened. She made it all up, including finding her "fiance" from a survivors book (whose friends say that he didn't ever date a woman named Tania) as well as created a lie about being saved by a heroic firefighter, who died. She even became close to his family.
I must say, this woman is a pathetic and cruel human being. It just disgusts me.
