The 9/11 Surfer (9 p.m., Discovery) is not a good title, but it's not meant to be disrespectful in any way.
It's the true story of Pasquale Buzzelli, who was on the 64th floor of the north tower of the World Trade Center when it was struck by a plane piloted by terrorists. He climbed own a staircase to the 22nd floor when the building collapsed - and he "surfed" the debris and ended up on top of seven-story pile of debris.
Buzzelli was rescued from there by New York firefighters. And in this hourlong documentary, he tells his amazing tale.
