American Airlines Flight 11 (visible in the upper right-hand corner of the photo) approaches the north tower of the World Trade Center on September 11, 2001. This largely unknown triptych (the subsequent images follow), shot from a Brooklyn window, was part of an ongoing Internet art exhibition that displayed updated panoramas of downtown Manhattan every four seconds. A time code can be seen in the lower right-hand corner of each frame.
In this picture taken on February 27, 1970, the south tower of the World Trade Center is under construction. The cranes of Koch Steel top the jagged structure. In the background, the north tower, is substantially more complete than its sister. @ALifetimeLegacy
