An Alaska company that makes a parachute system for drones came to Rome to conduct federal validation tests for its product. Indemnis sent a team to the New York Unmanned Aerial Systems Test Site at Griffiss International Airport in Rome in December to demonstrate its Nexus parachute system, according to a news release issued Wednesday by DJI, the Shenzhen, China-based maker of a line of unmanned aerial vehicles, or drones, and NUAIR. DJI has lines of drones for use in photography, film making, law enforcement, construction, agriculture and consumers. The companies began working together two years ago to develop a system that can deploy instantly if a drone gets into trouble. The U.S. Federal Aviation Administration prohibits most drone operations over people, but operators can get a waiver if they show they have safety measures.
