BOULDER, Colo. — University of Colorado researchers have come up with drone technology that might save lives.

A team of three spent weeks working on “swarming” technology that could help in searches for lost hikers and even the study of wildlife.

The advanced drone system allows one operator to use multiple drones. Tests were conducted at the Pawnee National Grassland near Greeley.

The goal of the technology is to locate moving radio beacons and follow them.

The university obtained a waiver from the Federal Aviation Administration allows one pilot to fly up to 30 aircraft at one time.
