Just maybe it could have been the publicity given to this memo that resulted in a rash of copycat incidents. The clown in New Jersey that was lasing aircraft is many things (none of them good) but terrorist is not one of them. The fact that none of these incidents has resulted in any injuries to pilots or passengers viewing the lasers indicates they aren't powerful. And weapons guidance lasers are not visible to the human eye.
I tend to agree with Rokke. It just seems rather silly that terrorists would try something that's such a longshot at working, just weaks after a terror alert about similar scenarios. Releasing the alert to the public an equally dumb idea.
None?
From the story: " the first officer of one plane whose retinas were slightly burned by the laser."
bttt
Blinding nonetheless.
