It was this day ( 11th May) in 1985 that 56 fans died in the Bradford City stadium fire. I remember watching this happen on World of Sport at the time . A terrible tragedy. It was later found that dropped litter under the stand which had accumulated over a long period of time was ignited by a discarded cigarette. The stand was mainly constructed in wood causing the fire to spread rapidly. A dark day for English football.
I knew someone who trained as a fireman in the late 80's and they were shown footage of that incident as part of their training, I believe it was still shown certainly up to fairly recently and may still be shown however he said they got to see some truly horrific footage that was never shown on TV.
I also met a guy about 10 years who was actually a Bradford player and on the pitch at the time, again he said it will stay with him forever seeing what he saw and being powerless to actually do anything meaningful to stop it
Incidents like this with an accumulation of litter and a fire from a discarded cigarette were apparently quite common at various grounds and other public venues but they were normally put out fairly quickly before they had time to spread and properly take hold, I believe a lot of the wooden stand at Bradford was also treated with an oil based tar / bitumen type coating to help stop it rotting but once that got fully ablaze it was game over.
AIR the Kings cross fire was also down to litter accumulating under an escalator and fire safety procedures have been changed to factor this stuff in and the requirement to check / clean these type of areas
Then just as you think H&S has gone mad and we could never suffer from any major catastrophe you get a shit show like Grenfell, I mean how the fuck was flammable cladding ever allowed to be used
