Amazon’s planned door-to-door drone deliveries sparked lawmaker worries Monday about the need for new privacy rules to protect consumers from thousands of drones that might soon be buzzing overhead.

Sen. Mark Udall (D-Colo.) said laws and regulations must keep pace with technological innovations that are turning science fiction into reality.

“Amazon’s experimental drone delivery system is just the latest example of how unmanned aerial systems have the potential to change everything from retail shipping to search and rescue missions,” he said.

“Coloradans will accept this technology only if they are certain their privacy is protected and that Americans won’t be victims of surveillance or privacy abuse by private unmanned aerial system operators.”

Sen. Ed Markey (D-Mass.), who has introduced legislation that would require federal privacy protection rules for drones, said those regulations must be in place “before our skies teem with commercial drones.”

The Senate Commerce, Science and Transportation Committee announced Monday that it will hold a hearing early next year on the commercial use of drones.
