It has often been stated that 9/11 was the first major event witnessed in real time by the entire world. As such, it had a huge impact on our collective consciousness and was a turning point in human affairs (no doubt just as intended). In recognition of this fact, we now use 'pre-9/11' and 'post-9/11' in the same way as we say 'BC' or 'AD'.
This photographic record, which I will add to as high-quality images become available to me, is intended to serve as a visual reminder of that day's catastrophic events and a suppliment to the rest of the information on this site [1, 2].
The World Trade Centre
The Pentagon and Shanksville
