In this composite image you can see New York City with a smoke plume still emanating from Ground Zero, one day after the 9/11 attacks, imaged by the Enhanced Thematic Mapper Plus (ETM+) aboard Landsat 7. The images were taken September 12th, 2001 at 11.28am local time.
Today is the 15th anniversary of the September 11 attacks (https://goo.gl/eT0C4j). The attacks on Tuesday, September 11, 2001 killed 2,996 people and injured over 6,000 others. In this image you can see a smoke plume still emanating from Ground Zero (https://goo.gl/PlRSN8) on Sep. 12, 2001, one day after the attacks.

For those interested, here the technical data for this image. The image is a pansharpened ETM+ Band 3-2-1 (natural color) image. The resulting colors are more or less natural but the brightness levels look unnatural because the panchromatic band of Landsat 7 (unlike that of Landsat 8) is also sensitive to the near infrared, changing the way the image looks. Image scale is 15 meters/pixel.
