It’s the most shocking and tragic day in American history, and it all unfolded on live television. After reports began to come in of a plane striking the World Trade Center, most of the major news channels began a live feed of what was then considered to be a horrific accident. When cameras caught another plane hitting the South Tower on national television, it became apparent this was a highly-orchestrated terrorist attack.

The image of American Airlines Flight 175 slamming into the South Tower was more than enough to let the world know that it would never be the same. Like the Kennedy assassination four decades earlier, people everywhere remember where they were at that moment, and for most, this live footage is something they will never forget.
