A while back Larry Silverstein was confronted and gave his tale that the radio tower was the culprit of WTC 7, even the diesel tanks have been targeted as of late. This spun tale not only doesn't make sense as the tower would have had to travel over 300 ft by some explosive force, but is contradicted by the antenna itself.

Here are pictures of the today as it stands in a Washington D.C. museum.
