This NASA image obtained on Earth Day, April 22, 2009, one of a series made following the terrorist attacks on September 11, 2001 showing a plume of smoke rising from the Manhattan skyline. This image was made by the International Space Station's Expedition 3 crew."The world changed today. What I say or do is very minor compared to the significance of what happened to our country today when it was attacked." So said Expedition 3 Commander Frank L. Culbertson, upon learning of the attack on the World Trade Center. Upon further reflection, Commander Culbertson said, "It's horrible to see smoke pouring from wounds in your own country from such a fantastic vantage point. The dichotomy of being on a spacecraft dedicated to improving life on the earth and watching life being destroyed by such willful, terrible acts is jolting to the psyche, no matter who you are."
