Marc Laidlaw points out this article from Sky and Telescope that has good information about the deadly laser pointers that terrorists have been using to knock aircraft filled with women and children right out of the sky. Oh, when will the horror end?
According to engineer Samuel M. Goldwasser, who maintains an extensive Web site about lasers called Sam's Laser FAQ, if you were to look directly into a laser-pointer beam from a mile away, it would appear as bright as a 100-watt bulb seen at a distance of less than 100 feet. Most people would find such a bright light very uncomfortable and would instinctively blink and/or turn away.
