Mega Disasters - Terrorist Attack World Trade Center September 11

Seconds from Disaster is an American documentary television series that
first began broadcasting in 2004 on the National Geographic Channel. The
program investigates historically relevant man-made and natural
disasters. Each episode aims to explain a single incident[1] by
analyzing the causes and circumstances that ultimately affected the
disaster. The series uses re-enactments, interviews, testimonies, and
CGI to analyze the sequence of events second-by-second for the audience.

originally consisted of 45 episodes over three seasons. Following its
original conclusion in 2007, the series was put in hiatus and was
replaced with Critical Situation. In 2011, National Geographic revived
the series, announcing it would air a new season from September 5, 2011.
