Drones are unmanned aerial vehicles that can fly autonomously or be piloted remotely, carrying payloads but no human. The US drone industry is an $82 billion market and will grow to 10% of aviation by 2025. Regulations require drones under 55 lbs to fly below 400 ft and within 5 miles of an airport with FAA authorization. Violations can result in fines up to $250k or imprisonment.
