VIDEO: On the day America marked 23 years since the Sept. 11, 2001 terror attacks, more people who helped in the aftermath became eligible to enroll in the World Trade Center Health Program.
The program expanded enrollment to include additional first responders who helped at the Flight 93 site and the Pentagon.
A retired law enforcement member and author who volunteered to respond to the scene of the crash in Shanksville shared what this expansion means to her and other heroes as she battles her own health issues, post-traumatic stress disorder and depression. Bells rang 40 times on Wednesday to honor the victims who died when United Flight 93 plummeted into a Somerset County field on Sept. 11, 2001, after passengers and crew members voted to fight back against a group of hijackers.
