Stanley Praimnath

[2] Whilst making a phone call from his office, he looked out of the south side of the building and spotted United Airlines Flight 175 flying towards him.

Praimnath froze up as the aircraft approached, unable to decide what to do, but at the last moment he dived under his desk just as the plane crashed into the building.

[3] Praimnath was bruised and exhausted, and covered in debris after the crash, which left him stuck and unable to escape on his own.

Later on that evening, after midnight, when Praimnath had finally gotten home from the hospital, he called Clark to find out what had happened to him.

The two men, who had never met before 9/11, remain friends and have appeared on numerous shows and documentaries telling their story.
