Purr of a Kitten - Power of a Panther The panther is unique in many ways. It packs more lightning power in its small, lithe frame than many animals of greater size. Much the same can be said of the 550 horsepower Ranger aircraft engine. The Ranger is the only in-line, inverted, air-cooled engine in production in America. Its sleek lines and narrow nose permit it to slip through the air with a minimum of drag, and in addition, give the pilot greater visibility. It is "lighter and quicker on its feet" than other engines in its power class . . . delivers more power for its weight. And then, it stands alone in still another respect: it is the one truly high-speed en- gine in its power class. The explosions that give life to its parts recur with such light ning rapidity that they blend into a velvety purr. Three hundred explosions a second! They sound like this /wwwwwwvw In other engines in the same power class they sound like this /VvAV/V \AVV Get the idea? Velvet power vs. jolting power. Hundreds of Fairchild engineers and tech nicians work day and night seeking still better performance through better materials, better methods, better designs for still better Ranger engines. It is these men who keep the Fairchild "touch of tomorrow in the planes of today."
