Didn't bother to cite the source here, but read in Pentagon reports that the fires on upper floors entered thru windows to the left (northwest) and maybe to the right - these burnt through the new section quickly (despite the brand-new sprinkler system), then quit burning there because of the sprinklers but raged thruh the secion to the northeast where there were no sprinklers.
No fire evident in inpact/renovated area may be explained by the windows - Russell Pickering says: "Remember the renovation line was just a few feet from the collapse zone. That is why you see fire coming through all of the windows north of the renovation line." The new windows were too solid to let the fire burn or sho through, the windows I guess too covered with soot - the old windows just melted and let fire flame out of them so it's visible.

Problem with this: No photos I've seen show fire on the third and fourth floors to the near,right, near-left, or center of the area above the plane's impact. It's all floors one and two as far as I can see. Gov. reports cite no burning right above the impact zone on the fourth floor - people there just walked out of the building. We didn't need to look through a windo to see, after the collapse, an unburnt stool right above the impact zone on floor three, a wooden desk on floor four, and file cabinet on 5, all untouched and unburnt. Dave Von Kleist pointed these out Tho he got the floors drastically wrong:
