Hard to believe, nearly 25 years later, that there is still footage of that horrific day that we haven't seen yet. But there it is:

A previously unseen video from 9/11 showing the Twin Towers collapsing has been posted online 22 years after the attack.

The clip was uploaded to YouTube by a man named Kei Sugimoto on July 23...

Mr Sugimoto says he chose to post the video now 'for historical purposes only' after he found the recording while clearing out a wardrobe.

Some younger readers might not understand it, but for those of us who were old enough at the time to witness these horrifying things, the footage of it always makes it feel like it happened yesterday:

In his YouTube post, Mr. Sugimoto explained why the footage took more than two decades to come to light:

To those who ask me why I did not immediately, submit the video to 'competent authorities' or get the word out, please remember that 2001 was a very different world from today. There were no smart phones, and internet access was mainly through dial up 56kbps connections using AOL or Earthlink. Google Search / Google maps / Uber didn't exist. After 9/11, public transportation was shut down and phone service was unreliable, the information available was mainly through the radio or word of mouth, and it was difficult to know what was true. There were talks of someone hearing that the Empire State Building would be next, and that all access in and out of Manhattan was blocked. I flipped through a physical phone book to figure out what precinct to go to and then roller bladed, as there was no other method of transportation. Upon arriving at the precinct, the staff had much more immediate tasks, and my offer to give them a video tape fell on deaf ears.

Thanks to Mr. Sugimoto for sharing the hard-to-watch, yet historically important footage.
