On the subject of last night's Best New Thing, Andy Dallos shared the above picture he took from an airplane window on Sunday and Bill remarked that we don't often see 1WTC from the sky like that where the height is so pronounced. Usually we see pictures from the ground, where the perspective makes it hard to distinguish the height of 1WTC from the surrounding buildings.
You may recall, the Twin Towers were visible from all over the city and were always a good way to orient yourself, for example when coming out of the subway. This new tower already has a similar prominence. At the end of that new cool time lapse video from the EarthCam people, below, they pull out to a wide shot that shows the height well.
