Chesley Sullenberger

After high school in 1969, I was appointed to the Air Force Academy. In '73, I studied for my postgraduate degree and became a USAF pilot in 1974. After my discharge in 1980, I became a commercial pilot and flew my first airline flight at Pacific Southwest Airlines in 1980.

Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.

Computers and computing are all around us. Some computing is highly visible, like your laptop. But this is only part of a computing iceberg. A lot more lies hidden below the surface. We don't see and usually don't think about the computers inside appliances, cars, airplanes, cameras, smartphones, GPS navigators and games.
