Show AIR PILOTS ARE TRAINED TO FLY BLINDFOLDED s Depend on Instruments and Directive Radio Beam. Chicago. A few miles to the west of the Chicago municipal airport an airplane appeared In the sky, the drone of Its engine steadily Increasing as It flew directly toward the field along the airway leading Into the Windy City from the Pacific coast As the plane soared by the airport, air-port, a field attendant on top a hangar spoke Into a radiophone: "Murray, you passed two hundred yards south of the field. Circle around." "O. K.," replied the pilot, who could see neither sky nor ground. The plane circled and once more headed for the airport. "You're coming straight toward the field now," the radio man advised, and In a moment the "blindfolded" pilot had guided the plane over the center of the airport. Pilot John Murray of United Air lines had flown the plane from Iowa City to Chicago without seeing anything any-thing except the instruments in front of him, for the cockpit was effectually covered by a hood. In another cockpit cock-pit without a hood rode Ralph Johnson, John-son, also a United pilot, but he didn't touch the controls during the entire flight All pilots are now trained In Instrument Instru-ment flying and the latest Inventions for air navigation have been Installed on company planes. The air transport trans-port company has recently been making mak-ing use of its radio telephone communication commu-nication between planes and the ground to lead the "blindfolded" pilots pi-lots directly to airports. With the aid of his Instruments and the directive radio beam, the latter a series of code signals Identifying the course of the airway, Murray was able to fly from Iowa City to Chicago without deviating from his course. When he arrived at Chicago, the airport air-port radio operator was able to lead him directly over the airport |
