CINCINNATI — Ohio and Indiana will operate their own test ranges for unmanned aircraft and seek ways of promoting more research and development to attract drone-related businesses after losing in their joint bid for a coveted Federal Aviation Administration test site.

The states sought one of six FAA drone test sites being set up as the agency develops a plan for safely integrating commercial drones into U.S. airspace. An industry-commissioned study predicted unmanned aircraft could produce thousands of jobs and billions of dollars in economic impact after that integration, and Ohio and Indiana were among two dozen states hoping that a site could boost their prospects for sharing in any economic boom.
