Scott Pelley suffers from the illness of Post-Traumatic Stress Disorder, also widely known as PTSD after witnessing the 9/11 attacks in 2001.
He exclusively talked about his experience of the horrifying event 20 years earlier.
According to Stamford Advocate, he was in the west street when the Twin Towers came falling down due to the plane crash launched by al-Qaeda.
Moreover, it was many years later when he found that he was suffering from PTSD from the event. Pelley has also revealed that he also suffers from anxiety and depression including PTSD.
It is likely that anyone who witnessed such a horrific event in life can suffer from mental illness.
The 9/11 attacks had claimed the lives of nearly 3000 people and brought down many historic buildings in the US.
