One good thing, nobody has to open up the roof
I think interior truck work will be the key to a good stop in this one. Quickly get a 1 3/4" line in with a couple ff w/ hooks to get the ceilings pulled.
I would knock down any visible fire from the doorway and then start pulling ceiling and pull it all the way through the house.
A backup line following the initial attack line is a must here, with the attic so involved, it would be very easy for the first line to get cutoff.
As far as layout, this appears to be a one story ranch from Side "Alpha" but as you make your way around to Side "Charlie" you can see it is actually two stories. Could cause confusion as far as "Division 1", "Sub-Division 1", etc.
How'd I do Boss, miss anything?
