Safety plans - including fire response... is not 'hindsight'
Their fire response that night was a guy with a hand held fire extinguisher -- that's not acceptable.
That fire got moving very quickly, and honestly, I don’t think they could’ve put it out entirely with just water. Look at the response to Notre Dame, they eventually put it out, but basically everything that was burning, burned. I’m not a firefighter, but at a certain intensity, the fire just has to run its course and it’s more about limiting spread, which they did successfully.
If a flame gets hot enough, it’ll just vaporize huge streams of water instantly, which probably would’ve been the case here barring blasting it with so much water damage would’ve been done regardless. They had the ability to put more water on Notre Dame but chose against it, because it could’ve caused the structure to collapse, but they still successfully isolated it, so more isn’t necessarily better.
But yeah, in hindsight, they could’ve had a better fire response/suppression system, but watching the videos, they responded quickly and it still went up in flames.
They could install a system like the one below, but they aren’t cheap by any sense of the word, but I’m not necessarily sure a few hoses scattered around the dragon would’ve helped.
You can’t just shoot large columns of water on an active stage occupied by people as it would pose a significant safety risk, beyond the fire itself, so before a system like that would even get activation, minutes would need to pass for the stage to get cleared (and by that point the dragon was already engulfed).
If TSI was engulfed in flames by the end of the night or many people were seriously injured, I would agree, but I don’t think that’s what we saw.
