If both the plain and the laser were absolutly still, the laser would have to be pointed with an angular precision of 0.0011 degrees. You think you can hold your hand steady to that precision? And keep it there for long enough to be a problem?? and without you or the plane moving by more than a cm???

Not saying laser filters are a superb idea, but anyway.

I'm STILL skeptical on two of the events reported- at ~10,000 m from the ground, I would think that the events over Colorado and Oregon would HAVE to be either plane-to-plane, or completely accidental discharge of an industrial laser.
