Nathan Flach

Nathan Flach (pronounced Flock) has been a major presence on YouTube in the 9/11 world for a long time, formerly known as Xenomorph911wtc, but now posting under his own name, Nathan Flach. He has been a major source and resource for those of us doing research based on the videos, but his recent work includes creating many stabilized and otherwise enhanced videos and bringing together meaningful montages of views that illuminate the details of the collapses. His collection is far too large to post here, but we have invited him to post a gallery of some of his more significant work on
