Gregg and Sir Bobby Charlton are the only survivors from 1958 who are still alive and the emotion was etched large on their faces, a reminder of the mental scars that persist, at a touching memorial service to commemorate the 60 anniversary of the tragedy at Old Trafford on Wednesday.

It is sixty years since the infamous crash that took place in Munich, where several members of the Manchester United football team lost their lives.

Manager Matt Busby's side were English champions and had reached the semi-finals of the FA Cup, and had defied the English FA to enter the European Cup, a newly created tournament between teams on the continent.

"The day that is absolutely shown in red on this week's calendar is on Tuesday, a day that marks the 60th anniversary of the air disaster", Spanish forward Juan Mata wrote in his blog on United's website.
"The victims will never be forgotten, they will always be remembered and will be a part of United's history forever". Our thoughts are with those affected by the disaster.
The Munich air crash that cruelly cut down Manchester United's "Busby Babes" in their prime has enormous significance for the club's players and fans even 60 years on from that fateful day. "Sixty years ago today, the Munich air disaster claimed the lives of 23 people, with many more suffering life-changing injuries".
"It was a really emotional time for anyone who was a football fan at that time".
