  configuration, an excess angle of attack pro- 
  duces a well defined stall. However, the 
  modern airplane configuration at an excessive 
  angle of attack has no sharply defined stall 
  but developes an excessive amount of induced 
  drag. To be sure that it will not go unsaid, 
  an excessively low angle of attack on takeoff 
  creates its own problems-excess 
  takeoff 
  speed and distance and critical tire loads.
