A video compilation of the world's tallest building demolitions uploaded to Youtube Aug 15, 2021, shortly before the 9/11 anniversary. The 3 obvious WTC building demolitions that day look remarkably similar to the 'collapses' in this video compilation, as noted by a remarkable number of commenters.

A 15 minute compilation of eyewitness statements about the destruction of WTC 1 & 2, including some from the FDNY oral histories released in 2005, news reports and footage from the 2010 NIST FOIA data release.

A lot of the footage will probably be familiar to you, but I used a few less well known clips here too. I made the aspect ratio of all the clips consistent, which will hopefully make them more suitable for others to download and use. Please share the video with others and I wish everyone well for 2016.
