Reply #6: The laser dazzlers for sale can easily reach airplanes.

[Alexander]

They have a range of 20 miles or something equally ridiculous.

I've used my friend's dazzler before, and if I wanted to, I could have easily used it on an airplane. If my hand was steady enough and I had good aim, the pilot might even see it, and in extreme cases can be blinded by it.

With the co-pilot and automatic systems, though, I find it hard to believe anyone could single-handedly take down commercial aircraft with this thing.
