31. Another common cause is failure of a tire or wheel brake, causing a loss of directional control . 32. Directional control was accomplished via thrust vectoring.33. Directional control was provided though two large mid-mounted wings which could be rotated independently to large angles.34. Just as important, however, is the use of sails, in combination with the rudder, for directional control . 35. The player may also move about along the roads through the normal directional controls provided by Street View. 36. Most control occurs by weight shifting, but pilots can also achieve directional control by using the foot rudders. 37. Four tailfins in a directional control . 38. Many of the planes employed wing warping for directional control , which involved re-discovering how to fly them safely. 39. The probable cause of the accident was that the pilot failed to maintain directional control when taking off. 40. The First Presidency's successful assertion of Supreme Directional Control allowed Frederick M . Smith to commence his Zionic endeavor.
