sentences:  Austin-Ball A.F.B.1
  
  The Austin-Ball A.F.B.1 (Austin Fighting Biplane) was a British fighter plane of the First World War, built by the Austin Motor Company with design input from Britain's leading fighter ace at the time, Albert Ball.Although trials with the prototype were on the whole excellent, and it could very probably have been developed into a useful operational type, the A.F.B.1 did not go into production, as both Austin's production capacity and its Hispano-Suiza engine were required for the S.E.5a.
