Respuesta :
The correct answer is B, as Colonel Billy Mitchell was court-martialed because he insisted that aircraft would be decisive in any future naval war.
William "Billy" Mitchell was an American aviator of French origin, who served in the US Army.
When a rigid airship of the Navy was lost in a storm (1925), he accused the US War and Marine Departments of incompetence; accused of insubordination, he was tried in a court martial and suspended from his duty. He resigned in 1926 but continued to defend the Air Force and warning of progress by foreign aircraft.
