Here is a picture of the WTC complex. Note the position of building #6 , between tower #1 and WTC #7, also note the location of #5.
Here is a picture of Building #7 ( to the right) with Building 5 burning in the background.
Here is a Pic of The burned out husk of #5 2 days later, the north tower scraped its side and the fires were started by flaming aircraft parts, even though it burned most of the day and had huge holes in it, it did not collapse.
Here is #5 with "Real" fires.
Here are the ruins afterward, you can see building #5 at the top of the picture, the heap that is the #1 tower is on the right. Building #6 is in the middle and even though a large amount of the North Tower fell onto it, it is still standing. Building #7 is on the left, a heap.
What do you suppose made this huge fucking hole? The N. Tower?
Here is an optical illusion. If you look carefully you can see Toronto's CN Tower in the background.
