This made me wonder Pictures taken out of airplane windows are crummy for two reasons, neither of which has much to do with the atmosphere. First, most commercial airplanes are taking off/landing from polluted areas. Second, the plexiglass used in airplane windows is really bad for photography. I'm not sure, but I think it has something to do with the weird filtering effects of plexiglass combined with the fact that human eyes and film respond to different frequencies of light Professional aerial photographers use special windows in their airplanes made of optical glass. I myself prefer to open the window of my plane when taking pictures and just stick the camera out. ed falk sun microsystems
