The little non-rigid blimps remained the neglected Cinderellas of post-war days. The Goodyear Company at Akron, which had built 1000 balloons of all types and 100 airships during and after the war, stepped into the picture during this period with a modest program of its own. The first of the Goodyear fleet, the pioneer, helium-inflated Pilgrim, now in the Smithsonian Institute, was built in 1925.

With a relatively tiny Goodyear blimp as escort, the Graf lands at Los Angeles after crossing the Pacific.] [Illustration: At Lakehurst the Graf tries out the “Iron Horse,” the U.S. Navy’s mobile mooring mast, finds it highly useful, utilized masting equipment thereafter to compile an unusual record for regularity of departures, even under highly unfavorable weather conditions.

Even the mighty Akron swings around easily at anchorage, heads into the wind like a weather vane, its control car resting on the ground.] In building this ship, Mr. Litchfield and his company indicated their belief in the value of big airships for trans-oceanic travel, for which the blimps would provide inexpensive training for pilots, and experience in operating under varying weather conditions. The Pilgrim, the Puritan, the Vigilant, the Mayflower and the rest of the Goodyear fleet which followed—named after cup defenders in international yacht racing—would also uncover during the course of day-after-day operations, improvements in ships and operating technique, which would be available to its customers, the Army and Navy. In building its own ships, Goodyear was following the tradition of American industry, which does not sit back and merely build goods to order, but has sought by developing better goods to anticipate and stimulate customer demand. In the automobile industry, for example, self-starters, closed cars, steel bodies, balloon tires, streamlining, and the rest were initiated by industry to increase public acceptance and further popularize the automobile. By building its own airships and flying them, Goodyear hoped to expand the market for military and commercial airships.
