Show Like Insect Flying. So far nearly all aeroplanes 'fly almost al-most like insects. The fly makes 300 beats of Its tiny wings a second. The propeller perhaps ciie-thlrd as many revolutions, but the albatross and the frigate bird and the buzzard make at most only three or four beats a second. But albatross and frigate can sustain themselves two or three days without lunching between dates. Let's hear of prizes for longer and longer flights on tho least gasoline. When the .thing gets down to brass tacks it may show that the aeroplane only needs to put on strong power In going up to Its aerie. After that it may soar away and use its gasoline only to meet certain unusual conditions condi-tions In the upper or lower air. |
