re: Lasers as a terrorist weapon
I think you're overestimating the power requirement. I've scanned some of the documents relating to military laser target designators. All of them discuss the possibility of eye damage if you shine them in someone's face. From what I've read, it only take a watt or so to cause at least temporary dazzling or damage. A small laser, probably less than 10 watts, aimed with a rifle sight might be enough to do the trick, depending on how much of the light penetrates the cockpit windshield.
