The FA Cup tie between Liverpool and Nottingham Forest was halted at 3.06pm
On 15 April 1989, 96 Liverpool supporters at the FA Cup semi-final against Nottingham Forest at Hillsborough never came home as they were crushed to death in what became England's worst football tragedy.
A special memorial service was held on Wednesday at Anfield to mark the 20th anniversary of the disaster.
Anfield remembers Hillsborough
Families of the victims, players past and present were part of the estimated 30,000 at the service which included a two-minute silence at 1506 BST - the time when the match was stopped.
Here, BBC Sport brings together the thoughts and reflections of those involved in, and touched by, a tragedy that changed the face of British football forever.
Details of the memorial service can be found on the BBC Liverpool website. Coverage will be available on BBC websites, the BBC News Channel, BBC Radio 5 Live, and BBC Radio Merseyside
"In the 20 years since, I have been blessed with a happy marriage, three children and a fulfilling career.
"What might the 96 have done in that time? What love affairs have never been, what friendships never forged, what children never conceived?
"The game has changed, and some say not completely for the better.
"But if you are lucky enough to be able to take your children to a match and sit in safety; to be treated with respect by those who police our grounds and to get home again without being crushed or scared, give those 96 a thought."
Hansen's 'bad emotions'
Many of the survivors and bereaved families are still waiting for those responsible for the events 20 years ago to be brought to justice.
An official inquiry, conducted by Lord Justice Taylor, blamed poor policing and inadequate facilities. But no-one has ever been successfully prosecuted for the tragedy.
"There's a lot of people who were in my situation who can't even talk about it,"
survivor Damian Kavanagh
told BBC News. "I think it's important that the truth is told."
"It's hard to go through it over again but it has to be done so people understand what really happened."
said the coverage of the day's tragic events in some newspapers at the time had left some deep wounds for the club and city.
"People will never forget that day - it's etched on our memories," he told Liverpool TV.
"That's probably what matters most - that people understood that the behaviour of Liverpool fans in helping each other was magnificent.
"That it was wrong for people to blame, as some did, Liverpool fans on that day. People have learned first of all not to rush to instant judgments. Some of the people who did rush to instant judgments have been proven wrong.
"Let's never forget the fans who cruelly lost their lives on a day when we know the people of Liverpool were trying to help each other."
manager of Liverpool's bitter local rivals Everton, said the tragedy united a city normally divided by football passions.
"It could have been any football club, it just turned out to be Liverpool. That situation then could have happened to anyone at that time," said Moyes.
"It is something that hopefully we will never see again.
"And for all the rivalry we have got between each other, blue and red in this city, it is only a game we play and you go to matches wearing your colours.
"I remember doing that with my dad as a young boy, a lot of parents take their children to games. But that time they did not come home, and that is something that should never have been allowed to happen.
"Let's just hope that it never does again. And in some way I hope for the people who have lost loved ones and had their time grieving, that the memorial service at Anfield will make it a little bit easier for them."
