O’Neil Group last month bought a majority interest in SEMCO, which employs 25 people in Carlsbad, Calif., to design and manufacture equipment that gathers and transmits data gathered at military and civilian flight test ranges for advanced aircraft, missiles, rockets and weapon systems. Kevin O’Neil said in a news release that O’Neil Group wants to expand SEMCO’s reach to help test ranges collect and use “all data generated across these ranges.”
