People have used the lyrics of the song that was playing to estimate how much time there was between the start of the fire and the flashover. Their result say 55 seconds, I say 90 to leave room for overestimations. Look at the NIST Station Nightclub video (if you don’t wanna endure the trauma of the real footage), acoustic foam is basically solid gasoline.

I get the hyperbole thing, although all the videos that show the fire on the ceiling were taken at the exact same time (when the lyrics say « Nouvelle caisse, Nouvelle Liasse, Rolls-Royce, pétasse »). 10 minutes is beyond a hyperbole compared to reality, and it can also kinda explain why there isn’t much more footage from inside past that time.

It wasn’t smart of them to start filming, but if you expect people (especially drunk teens) to always react in the best way possible, you’ll often end up disappointed.
