Manning remained conscious despite her injuries and watched as the second plane was crashed into the South Tower. Having been at the World Trade Center during the 1993 bombing, Manning recognized that this was another terrorist attack. She recollects that she "made the decision in those moments to live." She was forced to re-cross the street to board an ambulance, which had pulled up to the burning building approximately 40 minutes after the attacks began. The ambulance did not depart until approximately ten minutes before South Tower collapsed. Manning had suffered an 82.5 percent total body surface area (TBSA) burn, with 75 percent of those burns third degree.
