AN AVIATOR S SIGN-POST FOR NIGHT FRYING 



"Signal equipment consists of four- or six-light projectors with red or green lenses. They 

 are mounted on angle-iron frames four feet square, standing three feet high. Each unit has 

 an automatic flasher system attached. For indicating the direct flying route from Dayton to 

 Rantoul, lights flash on and off at about six-second intervals." 



AN AVIATOR S LANDING FIELD INDICATED BY HUGE NUMERALS PAINTED ON 



THE ROOF OF A BARN 



_ The initial program for a well-marked air route from Dayton, Ohio, to Rantoul, 111., 

 designed as an aid to the training of aviators, includes the painting of large white figures on 

 barn roofs, with arrows pointing in the direction in which the birdmen can find safe landing 

 places.
