not to go down a rabbit trail here- but thats exactly what SHOULD have been done. Ladder companies ALWAYS vent the exterior (either vertically thru the roof or horizontally thru the windows) AS the Engine companies make entry.
Doing so removes most of the heat and smoke so your interior crews don't take a beating, and drastically improves visibility. Otherwise, it would be like walking into an oven. Also, you need to vent on the opposite side of the structure so you don't get blasted AS you make entry (anyone see "Backdraft"? thats what happens when you dont vent)
I'm telling you- unless it was a torch job and something was done to accelerate the process, it was probably a truss failure- one minute the building is up, the next is down and you can't outrun gravity. Truss roofs are rated for about 20 min under heat/flame impingement, so that gives you 5-10 minutes AT MOST to work in there (assuming it took 5 minutes to discover and report the fire, and another 5 to get there and make entry. Those are GOOD numbers, and still BAD odds. Some times we lose the bet)
I apologize for the detour- the media has a way of giving bad impressions. So very sorry about this whole thing.
