For defensive operations it can't be beat. If you are using a squrt you can go though a window or the roof if it's burned off. If you have a platform, cut the roof and shoot through the h*** or lower the ladder to the level of the effected rooms and blast them.
Two things; don't mix offensive and defensive. Before you fire the master stream up, INSURE that you have evacuated the structure and have a good PAR. Second, watch how you hit the structure. You don't want to over shoot and hit exterior crews and you don't want to hit a part of the structure (chimney or exterior wall) and have it drop on a crew.
PS. what was the issue?
departments use Aerial devices at residential fires every flippin day. If you need big water you go to where you can get it. The people watching will probably be pleased as punch that you brought the big guns.
