Do you remember where you were on August 31, 1997? It was that day, 20 years ago, that the world tragically lost Princess Diana in a preventable car crash.
Prince Harry was just 13 years old when he lost his mother, something that still haunts him to this day.
Up until now, Harry has been fairly quiet surrounding his mother's death. Some speculated that losing her is what drove him to his crazy party antics, but as he's grown up it's clear he is trying to follow in his mother's footsteps.
Harry recently opened up with his brother Prince William and sister-in-law Kate Middleton, discussing how he sought counselling after his mother's death.
But perhaps the most outspoken he's been about her accident is for a new documentary airing on the BBC, as part of a 20th anniversary of Diana's death.
On that dreaded night, Diana was travelling in Paris with her lover Dodi Fayed. They were in the back seat of a car that was being chased by paparazzi through a tunnel. The car crashed, leaving both Fayed and Diana with fatal injuries.
But Prince Harry says there may have been a way to help her.
"I think one of the hardest things to come to terms with is the fact that the people that chased her into the tunnel were the same people that were taking photographs of her while she was still dying on the back seat of the car," said Harry.
"She'd had quite a severe head injury but she was very much still alive on the back seat," he added. "And those people that caused the accident, instead of helping, were taking photographs of her dying on the back seat."
He believes that had she gotten help sooner, her death may have been preventable.
The entire documentary will air on BBC One at 7:30pm BST on Sunday, August 27th.
