Flight Safety Technologies of Mystic, Conn., is developing two hazardous warning systems–Socrates and Unicorn. Its Socrates wake-vortex detection and tracking technology is slated to be tested for a month at Denver International Airport starting August 15. Unicorn is a collision avoidance system designed particularly to prevent midairs between piloted airplanes and government-operated unmanned aerial vehicles. Meanwhile, Flight Safety Technologies denies that there is a conflict in company names claimed by FlightSafety International.
