it will construct the seadromes just as soon as steel is available.

Penn Central wishes to fly the route, but Mr. Monro 

 stressed the fact that all air lines even private flyers would 

 be permitted to use the seadromes. "Our seadrome idea has 

 been proved sound," he added, "and we hope to get permis- 

 sion to install them as soon as victory has been won. Immediate 

 postwar employment for thousands in the steel mills and ship- 

 building yards, in their construction and transportation to 

 fixed points at sea, will result. When successfully installed and 

 in operation the seadromes will give valuable aid to shipping 

 by providing hour-by-hour weather reports and forecasts 

 never before obtainable. Light planes for iceberg spotting also 

 could operate from the seadromes. Plans no doubt will be 

 developed for more and more of them for the Caribbean, 

 Pacific, South Atlantic and everywhere they can be put to 

 good use and for use of all." 



Passenger Stratoliners 



In the not-too-distant future, passenger-carrying strato- 

 liners that fly at forty thousand feet, far above storms and 

 dangerous icing regions, will be used extensively for global 

 service. A number of new inventions now make this type of 

 service feasible. One is a device patented April, 1943, that 

 prevents the formation of ice on the leading edges of wings 

 and propellers. It mounts a pair of infrared radiators on the 

 sides of the plane's nose. They are focused to throw their 

 beams on the leading edges of the wings. This "sun-lamp" 

 treatment keeps the wings warmed above the icing tempera- 

 ture at all times. (The most dangerous temperatures for the 

 formation of ice on airplanes are those between 20 and 34
