A target 6 miles out, 3000 feet up, and moving at 600 mph. You'd have to have a very steady hand to hit that target.
The plane here in Cleveland reported the laser 'tracked' them on landing. They were btw 8500-10000 ft. going 300 mph. On the other thread http://www.freerepublic.com/focus/f-news/1310958/posts
someone discussed how this could be done. The other point is some of these are pulsating green lights which tend to put them in the military relm. China has made available a laser on the open market called a ZM-87, it's readily available in the third world.
I agree, with more reports finding their way to MSM, we may see some copycat stuff. But if one googles for information you'll read about reports from September of 2004 in which pilots received eye damage from this. This has been going on for a while.
If the pilots doing 600mph at 3000 feet he might get arrested also(max. 250kt(288mph) below 10000)
