AN AVIATION SCHOOL MACHINE FXYING OVER BISCAYNE} BAY, FLORIDA 



Speed, handiness, and great climbing ability are three essential qualities in a warplane. 

 A machine admirably constructed for fighting at low altitudes but ineffective at an elevation 

 of two and a half miles would be worthless, for in modern air battles it frequently happens 

 that the scene of conflict is four miles above the trenches. The quality which a fighter most 

 values in his machine is "handiness," of which speed is one of the chief factors.
