Exclusive: Ad drones launch over Miami Beach

Why it matters: Sustainable Skylines says it's the first company of its kind to receive Federal Aviation Administration approval.

• The company says its hybrid drones are safer for pilots, less noisy and more environmentally friendly than traditional banner planes.

Yes, but: They will also fly 100 feet lower than typical banner planes.

Zoom in: The company's existing fleet of two hybrid drones, which are about 5.5 feet in diameter and weigh just under 100 pounds, will take off from Virginia Key and follow a four-mile flight path along Miami Beach.

• The drones tow 800-square-foot banner ads. On Friday, the company planned to fly an Ad Council ad raising awareness about the dangers of buzzed driving.

What's next: Sustainable Skylines plans to expand to other states.
