A brief science lesson

SOME OF MY OLDER POSTS ON THE PENTAGON AND FLIGHT 93 HAVE BEEN DELETED SO I WILL REPUBLISH THEM IN THE COMING DAYS..IT IS OLD NEWS TO SOME SO FOR THEM I APOLOGISE FOR THE REPOSTS.I WILL MAKE THE POSTS BRIEF AND PROVIDE LINKS TO EXTERNAL SITES TO KEEP IT SHORT (DREW: Webmaster)
The commentator in this short video explains why it could have been a missile that hit the Pentagon.I know this is a very popular theory and the guy in this clip says that it was definitely a missile but, do your own research. A very interesting clip all the same.
