Dahm, director of the laboratory, said in a New York Times report on the article that he is reluctant to predict when the laser could be used practicably in the news and notes two warning systems or how much such systems could cost. About $650,000 will have been expended when the first airborne clear-air-turbulence warning system is tested. A carbon dioxide gas laser is being used as the power source for the warning system. It is designed to measure atmo- spheric wind velocities directly and provide the airplane Lasers beam in on CAT and aerial vortices cockpit with an indication of turbulence.
