'GUARDSMEN' OF THE SKIES.

'GUARDSMEN' OF THE SKIES. The United States Army Air Corps is celebrating this month the thirtieth anniversary of its foundation - which occurred with the purchase of a Wright Pusher-type biplane. In the years between the corps has grown so that in a short while its total strength will be 5,500 warplanes. Here is an impressive picture of a squadron of America's latest fighter craft, strung out in perfect alignment, during rehearsal of a 'fly past'. They are Seversky machines.
