If you were worried that the Federal Aviation Administration would require a pilot's license before you could fly a drone for professional reasons, you can relax... well, sort of. The FAA has published its proposed commercial drone rules, and they're a bit more lenient than some had feared. The good news? You wouldn't need a license to fly any drone under 55 pounds; instead, you'd take an "aeronautical knowledge" (read: airspace rules) test every two years and get an operator certificate. And if you're flying model airplanes that fit existing criteria, you'd only be bound by current laws.
