WTC 4,5, and 6 [View All]

I'm trying to resolve the following three images.

The first is FEMA 5-17, which FEMA uses to support its assertion that fires
brought down WTC7 (even though pictures of the N, S, and E sides showed
only wimpy fires).



One analyst dismissed the smoke as dust from the WTC1 collapse, but the sunlight
on the western walls shows this picture was taken in the afternoon.



The second is FEMA 4-13, showing building 5 on fire. That looks like enough
smoke to explain the smoke in 5-17. Does anybody know what time this picture
was taken?



The third purports to show WTC4 on the left and WTC5 on the right. Note the
sunlight on the east wall of WTC7 in the background, and the lack of sunlight
on the south wall. This suggests that the fire in WTC5 had burned out early
in the day. I suppose new fires could have broken out later in the day.

So.... does anyone have information about the fires in WTC5 and WTC6?
Does anyone know the history of the third photo?

Is it possible the fires burned out early in the day and then reignited
later?
