Read carefully! NOT shooting AT aircraft but FROM an aircraft. Is it illegal to get on a commercial plane (like a 747) and then take the green laser out from your pocket and fire it out the window to the ground bellow?
It would be pretty cool and people would think their getting attacked by aliens and theirs no risk to blind people because at that range you would need a laser much bigger than pocket sized. To get it on board you would put it in your carry on and then open it once you got inside the jet and take it out. You should not just put it in your pocket because it will probably make the ringer sound and then if they search you and see the sticker on it or try it out and they see the green beam they might take it away from you.
