This is one of the best pieces done on the whole issue of unresolved questions surround the events of September 11. Unlike so much of what is referred to as “Truther” material, which all-too-often makes speculative declarations and uncorroborated assertions, this video, featured on PBS, asks the right questions and only talks about what it knows.

Highly recommended for any and everyone who has questions (or hasn’t even considered the questions) about how the three buildings at the World Trade Center complex all fell that day.
