Not sure if I posted before but I was within a couple of hundred metres of the Address hotel blaze in Dubai 18 months ago, it happened on Hogmanay very close to the Burj Khalifa firework / laser show. From first noticing the fire on the lower 2 floor balconies to it being a 20+ floor blaze took literally 2-3 mins. Cladding was the cause of speed of spread or if I'm not remembering wrongly, more to do with the epoxy that fixed the cladding? It's now unlawful to attach non fire retardant cladding and new cladding has to be retro-fitted to buildings over a certain number of floors.
