[Illustration: Kelly Field, established during World War I, is the oldest advanced flying training school in the nation. The dull gray frame hangars and buildings erected at that time still constitute most of the field’s structures, although in recent years many fine permanent type buildings like the Cadet Barracks pictured here, have been erected.] [Illustration: Most of America’s great aviators of the past quarter century received their “wings” at Kelly Field. Ground school study at the field is now carried on in this new Academic Building.] [Illustration: Randolph Field, “The West Point of the Air”, is one of the largest military airdromes in the world, embracing a total area of approximately two miles square with the building area occupying 475 acres of this. Here are located the primary and basic flying schools of the Air Corps, U. S. Army. The key structure of the field is the Administration Building pictured here, which has a tower 175 feet high, topped by a powerful beacon to help orientate night fliers.] [Illustration: A portion of Randolph Field looking south from the top of the Administration Building. The home in the foreground is that of the commanding officer of the field.] [Illustration: Randolph Field from the air.] [Illustration: Two of the Cadet barracks at Randolph Field. The Spanish type of architecture has been followed consistently in all the construction at the field, with the exception of the hangars.] [Illustration: Another Cadet barracks.] [Illustration: The Randolph Field Post Chapel.] [Illustration: Sailboats.] $1.25 _San Antonio_ _City of Missions_ By CLAUDE B. ANIOL Travelers who have visited San Antonio remember it as a city with a warm and personal charm. It is one of the rare places which embody and symbolize all that is America. Founded by the Spanish in the late seventeenth century, San Antonio has flown the flags of France, Spain, Mexico, the Republic of Texas, the Confederacy, and the United States. In the midst of an important city which is a center of industry and commerce stand the lovely 200-year-old missions, and the Alamo, whose defense by Bowie, Crockett and their fellow heroes gave birth to a great rallying cry of our nation. Nearby are the aviation stations of Randolph, Kelly, Brooks and Duncan Fields, “the cradle of America’s air might.” _Claude B. Aniol, one of America’s foremost photographers, is eminently qualified by his intimate knowledge of San Antonio, his home, to portray in superb photographs this dynamic and busy, yet always picturesque city._ _American Guide Series_
