Aviation history begins a new chapter Eight days, 15 hours, 51 min. aftei they had taken off for Harbor Grace on the first leg of their round-the-world flight, Wiley Post and Harold Gatty landed again on Roosevelt Field. Their Lockheed-Vega monoplane, the Winnie Mae of Oklahoma, had covered 15,474 miles at an average speed of about 146 m.p.h. Flying over some of the most hazardous seas and least known countries of the globe at heights varying from 11,000 ft. to barely enough to clear the surface of the ocean, they shattered all previous records.

Reaching a Private Market with Flying Clubs

It can be done. Though flying club operation has not attained much success in this country, the experiences of a number of individual groups convince us that the method is fundamentally sound.

Fifteen Years of Aviation

FIFTEEN years is a very short time in most human affairs, but in aeronautical matters it is a long one. It is a long enough period to give historical perspective. It is long enough to have covered two or three generations of airplane design, within each of which machines have passed from the status of greatly admired mechanical marvels to that of museum exhibits.
