"It involves multiple watts of lasers, though." It never fails to amaze me that if you can prove you gave the FAA the legally required minimum 30 days warning you can do anything up to death star experiments and they can't say boo about it, but skipping the paperwork and trying to beg forgiveness after the fact is like a dozen separate felonies, so be careful. Assuming you're doing what I'd do with many watts of lasers, LOL.
