I have a personal story of this, actually, not in an aeroplane but just at home. Someone was shining one of these lasers through the windows of my house late one night, and the risk, of course, was that it would blind either me or my wife, who were both up in the house at that moment. Of course, we could sort of identify roughly the position of where the person was who was shining the laser into the house, and I sort of went out on to the deck and the person disappeared.
