Well I was QM, no one got it - the answer was Burnden Park 1946 and and the report after required the installation of public announcement systems are sporting stadia as the 33 people crushed to death only happened in one corner of the ground, the ref wanted to adandon the game but feared further crushing if he did, so the game continued. Indeed at HT the teams just changed ends and carried on as no one in the farthest parts of the ground had a clue what happened.
Stan Matthews played in the game Bolton 0-0 Stoke City, and mentioned it in his biography, that he had to retrieve the ball from amongst dead people laid out in the old Burnden running track, he never forgot it.
My dad was there as I said, in that same area, no ticket, was allowed in as he had sold the programs he had to sell for entry, no space on the terraces, had to sit on the running track, 10 mins after kick off, sat amongst dead people laid out. 13 yo.
I remember my dad telling me that he could see all the people in the Railway Embankment End heads' were all in perfect lines, such was the amount of people crammed in.
Watch this.
