In the movie of War Fog, about Robert McNamara, fmr Sec US of Defense, he describes his role under the command of Gen Curtis LeMay who was in charge of bombing campaign over Germany. He noticed that there were lot of mechanical problems in the the report of mission. He surmised, and the statistician found out that these problems were not real. The flight crew were terrified. With a mortality rate of 5% and 20 sorties in the service period of most crew, the crew would surely die. So they created all excuses not to go.
Gen LeMay had a solution to this. He would personally lead the mission; and the mechanical problems were dramatically reduced
That is what leadership can do..
