for months afterward, folk who lived downwind--our daughter and her husband were among those, living in Park Slope in Brooklyn--had the classic symptoms of very bad air. Hi John, I am sure some folks were affected. Sorry it was your family. I studied the WTC fallout for a presentation I give on escaping from fallout zones. The wind was blowing briskly from the NW in NYC on 9/11. The fallout plume was substantial but moved SE and right out of the area from the Southernmost part of the island where the WTC was located. The areas of Manhattan significantly affected by fallout were S of Canal St. A very small part of the island. Some did blow across part of Brooklyn...but very quickly and then it moved out to sea. Affecting a narrow swatch of Brooklyn. Overall it is pretty amazing how little of NYC was affected by the plume...that was due to the brisk wind. The prevailing winds in NYC are Southwesterlies and they resumed that direction some hours later, blowing the last of the fallout quickly to the NE, and only after the bulk of the fallout from the collapse had been blown out to sea, sparing Brooklyn more fallout. Unlike a nuclear detonation most of the WTC fallout came from the buildings collapsing and it dissipated rapidly. There was also some residual smoke for for quite a while but the pictures I have seen of that always show it moving up into the atmosphere...never hugging the ground. By the time the EPA or whoever got around to examining air quality...it was most certainly acceptable. Though it was probably horrible initially. I have a satellite image of the WTC plume that I use in one of my classes. It is elongated and very narrow, indicating a very brisk wind condition that kept the fallout in a very tight airborne formation. It was not wide spread as some are trying to say. Be happy to e-mail the image to you. It is in powerpoint format and clearly shows the WTC and the plume. My fallout zone calculator fits the plume or fallout zone perfectly. There are some excellent aerial photos at this link...Scroll about 2/3 to 3/4 down the page for a series of several photos that clearly show just how small and narrow an area was affected. One early photo clearly shows much of the heavy debris dropping in the river before getting to Brooklyn. The pictures are just posted and not necessarily oriented correctly to N. For reference the WTC is actually in the SSW part of Manhattan and the island is generally oriented N-S. 911ea.org uw
