Check out this video from Raleigh, NC. The fire is in a residential house build with lightweight construction. The view from the video doesn’t offer us everything that is going on, but you can get the gist of it.
All the while, a firefighter (from some other department) is giving his friend answers to his questions about what is going on. At first it seems as though there is a delay in getting water. However, I think that after watching the video, the firefighters actually go inside and then are called out when the exterior operations are set up.
