Question of the Week
Are FAA drone rules too restrictive?

This week's Question: This month, the Federal Aviation Administration proposed long-awaited rules on the commercial use of small drones, requiring operators to be certified, fly only during daylight, and keep their aircraft in sight. The ruling, for now, prevents drones from being used for a range of possible...
