Video shows rescue workers help an injured hiker get down from atop of 400-foot cliff with a drone

A 65-year-old woman in Utah's Snow Canyon State Park got some unexpected help from a drone operated by the local sheriff's department, after injuring her ankle while hiking with friends. While walking near the edge of Island in the Sky, a famous canyoneering and rock climbing route, she slipped and fell several feet, injuring her ankle to the point where she could no longer stand or support her own weight. The group of three friends she was with called the sheriff's search and rescue team rather than attempt to carry her back down the steep and sandy trail themselves. Search and rescue workers from the Washington Country Sheriff's Department in Utah used a drone to deliver then 660 feet of twine to help setup a rappelling system to get an injured hiker down from a clifftop The sheriff's team decided to bring the woman down from the 400-foot-tall cliff, the equivalent of 40 stories, by strapping her to a stretcher and using a rappelling system to guide her down. The only problem was they didn't have enough rope to reach actually reach the ground.
