Not just no aircraft in the US, no aircraft in the world has had anything more than a pissed off pilot at landing.
You seem to be arguing like I'm saying people should target aircraft at landing with lasers, its no big deal. Re-read what I said... I mentioned at least twice that you shouldn't do this. Stupid kids do this sort of thing. But this is heading in a very predictable direction. They are trying to ban consumer lasers with this lame excuse. Is there a possibility that the right laser, hits the right pilot, and distracts him enough that it really does cause some sort of problem? Yes it's remotely possible... but the chances are so remote that I feel safe in saying it will never happen.
But like I said, if you want to be ultra-super safe... install polarized plastic lenses over the windscreens. Remember we used to stick them on laptop screens? They cost about $5 each. But they haven't done that yet... why? Because the risk is so remote it's not even worth spending $5 to protect against. Do you think the owners of multi-million dollar jet liners would risk their aircraft when the fix was so simple if it were really a threat?
