In these three states more than 200,000 acres of farm crops were dusted by plane during the past year. UNIQUE OPERATION One of the nation's most unique flight operations is going into its third year of successful service. John Riedl, manager of the Hey-wood-Gull Lake airport at Nisswa, Minn., recently completed two years of power line patrol for Minnesota Power and Light company. During that time he has flown 25.000 miles in a Piper Cub, flying a few feet above the 100.000 volt lines, which run north to the Mesabi iron range over heavily wooded country. I In contrast to foot patrols, which required re-quired six weeks to inspect the com- . - ....v.. uiv wwm- pany's lines, Riedl and his observer, observ-er, John Mattson, make regular trips over the entire line every other week. Damage from lightning, forest fire, windstorms and fallen trees are among the causes of power failure which must be watched. Most frequent fre-quent trouble spotted by the aerial observers, however, is broken insulators insu-lators atop the 60-foot poles which have been shot at by trigger-happy hunters. NOT A CRASH! . . .
