Danger, not nuisance
From a geeks forum: "Pointing lasers into the sky and outside in general is one of the best ways to show off and have fun with them after it gets boring burning stuff with it. If done safely it's harmless and great fun. Any pilot who would get distracted just by seeing a beam pointing into the sky and crash probably shouldn't be flying to begin with."
What about T/O and Landings in night?
Oh, my... too
