The history of what happened on 9/11 is etched into almost everybody who was alive that day's mind.
And the story of flight United 93 which crashed into a field in Shanksville, Pennsylvania, avoiding the nation's capital, thanks to some brave passengers is a part of the narrative that most people are aware of.
But the widow of one of the pilots on board that fateful flight has spoken out ahead of the 20th anniversary of the atrocities as she feels her husband's story has been hijacked.
Melodie Homer's husband LeRoy Homer Jr was the first officer in the cockpit of United 93 as terrorists on board stormed the cockpit.
He raised the alarm, made a MayDay call from the flight deck, fought with the terrorists and lost his life trying to save the plane and all those on board from going down.
His part on that day is rarely acknowledged.
Melodie, taking part in the BBC documentary Surviving 9/11, said the story of the passengers storming the cockpit to take out the terrorist was one the world needed to hear in the aftermath of that dreadful day.
She said: "It was a story that everyone probably needed to hear, and wanted to hear.
"None of the crew are mentioned in their narratives.
"People would say to me, 'there was a black pilot on that flight?', that's how little they knew about who was in the cockpit and that's a huge part of the story."
She added: "It felt like that was a hijacking of everybody else's stories and everybody else's grief.
"I feel protective of LeRoy and I feel protective of his legacy."
LeRoy had wanted to be a pilot from a young age and it was his dream to work for United Airlines.
He was a soft spoken man with an ever-present smile; his friends described him as having a heart of gold and he was one of nine children, growing up with seven sisters and a brother.
LeRoy completed his first solo flight at 16 and by the time he entered the US Air Force Academy, he had a private pilot licence.
He graduated from the US Air Force Academy and began a military career flying C-141s.
He served in Desert Shield and Desert Storm and received commendation for flying humanitarian operations in Somalia, an assignment that put his life at risk.
During his active service in the US Airforce, LeRoy achieved the rank of Captain and later became a Major after he entered the US Airforce Reserves.
LeRoy joined United Airlines in 1995.
Melodie is now president of the LeRoy W Homer Jr Foundation, which was founded in 2002 in memory of her husband.
The mission of foundation is to encourage and support young adults who wish to pursue careers as professional pilots and increase awareness to the field of aviation.
Since it began, 27 scholarships have been granted.
