Why was colonel billy mitchell court thrown out of the us army

He was court-martialed on the charges of insubordination and insisted that the Navy should build aircraft carries rather than battleships. He believed that these new vessels would be vital when war would occur. In a way he was proven in World War II when aircraft carries were instrumental in many victories at sea.
