Tragedy struck Manchester United on February 6, 1958.
Eight United players and three staff, as well as eight sports journalists including the Manchester Evening News' Tom Jackson, lost their lives in a plane crash in Munich, Germany, as the team were returning from a European Cup game against Red Star Belgrade.
Twenty-three people died in total as a result of the tragedy, including United greats Duncan Edwards and Tommy Taylor, and City's legendary goalkeeper Frank Swift.
Manchester United had been to Yugoslavia to play in a European Cup tie against Red Star Belgrade. The squad and others on board set off for home on a chartered British European Airways plane the following day - February 6, 1958.
The aircraft, an Airspeed Ambassador 2, stopped in Munich to refuel. Engine issues led to two aborted takeoffs following refuelling.
By the time a third take-off attempt was made, snow had covered the runway with slush, and the aircraft crashed through a fence at the end of the runway and into a house.
Seven players died at the scene - Duncan Edwards died in hospital a fortnight later, while others including Bobby Charlton and manager Sir Matt Busby were gravely injured but would recover.
The crash was originally blamed on pilot error and German authorities embarked on legal action against Captain James Thain, who survived the crash (the other pilot, Captain Kenneth Rayment, died from his injuries).
Subsequent investigations, however, determined that the slush on the runway had slowed down the aircraft, leaving it with not enough speed to leave the ground and not enough runway to abort take-off.

What the survivors said:
Bill Foulkes: "As we accelerated down the runway, something told me we were not going to make it. My last memory is of pushing a pack of cards into my pocket."
Sir Bobby Charlton: "I didn’t know where I was. I was still sitting in my seat - which had somehow been ripped from underneath the plane. I thought I’d just closed my eyes. Afterwards, Harry Gregg and Bill Foulkes said I’d been unconscious for quarter of an hour."
Harry Gregg: "There was no screaming, no sounds, only the terrible shearing of metal. Something cracked my skull like a hard-boiled egg. I was hit again at the front. The salty taste of blood was in my mouth. I was afraid to put my hands to my head."
Back in the days before 24-hour breaking news, newsreels were often the way that audiences saw the first images from a news event. Many of those reports are now available to watch on YouTube.
