The earliest known video has surfaced showing the immediate aftermath of the crash of United Flight 93 in Shanksville, Pa.

In the modern world of viral crowdsourcing, video and photos of even the most mundane event are available, from every conceivable angle, with lightning speed, so it is remarkable that, ten years later, new video from 9/11 has just surfaced. On CNN Sunday night, anchor Susan Hendricks introduced a piece of video from a now-deceased witness who videotaped the aftermath of heroic Flight 93 from about 15 miles away. His family has apparently just made the video available now.
