The level of danger presented by l@sers can be gauged by the incidents reported in real life. To my knowledge l@ser illumination has not caused anything other than a minor irritation to the crew
Unless you're a master of understatement, you're wrong - a few have already suffered permanent damage to the cornea. Admittedly very few, but I can't see (no pun intended) why that should be tolerated, or downplayed. And it's neither "incidents" nor "accidents", it's assault causing bodily harm. I applaud every measure taken to stop it.
perhaps a reflective film on the aircraft windows to prevent the beam from getting inside.
I've wondered about that as well, but the problem is that current coatings, if you want to block all common laser wavelenghts, block too much of the entire visible light spectrum as well. Defeats the purpose of a window. Glareshields/visors or goggles are a better compromise, but really shouldn't be necessary to deal with lasers.
