William Rodriguez says he heard an explosion at the WTC “just seconds before” the plane hit.

Declared a hero for saving numerous lives at Ground Zero, he was the janitor on duty the morning of 9/11 who heard and felt explosions rock the basement sub-levels of the north tower just seconds before the jetliner struck the top floors.

He not only claims he felt explosions coming from below the first sub-level while working in the basement, he says the walls were cracking around him and he pulled a man to safety by the name of Felipe David, who was severely burned from the basement explosions.
