the attack was canceled due to adverse weather conditions, for the aircraft piloted by then lieutenant-aviator Ricardo Kirk suffered a crash, of which he was killed. Ricardo Kirk was the first Brazilian Military Aviator. In 1891 he entered the Military Academy and was commissioned an ensign in November, 1893 and to first-lieutenant in March, 1898 and posthumously to captain in 1915. Air actions of the Constitutionalist Revolution Although the two sides in struggle had few airplanes during the Constitutionalist Revolution of 1932, aviation made a big impact during the conflict. The federal government had approximately 58 aircraft divided between the Navy and the Army. On the other hand, the Paulistas had only two Potez 25 and two Waco planes, in addition to a small number of tourist planes. At the end of July, the rebel government obtained another plane, brought by Lieutenant Artur Mota Lima, who defected from Campo dos Afonsos, Rio de Janeiro. The "reds", as the federal government planes were known, not only acted on the lines of combat, but also were used to bombard several cities of São Paulo, among them Campinas, where they caused great damage. They also served as a propaganda weapon, dropping leaflets on enemy cities and into rebel concentration camps. For the use of aerial means, General Góis Monteiro had in his Staff of two advisers, Captains Vasco Alves Secco and Carlos Pfaltzgraff Brazil. Major Eduardo Gomes, commander of the Joint Aviation Group, who since the outbreak of hostilities had coordinated the employment of his unit and the reinforcements of the Military Aviation School, was designated, on September 16, Commander of the Air Units of the Army Detachment of the East. On September 6, Major Ajalmar Vieira Mascarenhas was appointed Commander of the Air Units of the Detachment of the Southern Army. The Navy's aircraft were under the direct operational control of the naval authorities, operating in support of the surface ships deployed near the port of Santos, to effect a naval blockade and also in support of the Naval Flotilla of Mato Grosso, based in Ladário. They also participated in operations with Military Aviation in the Paraíba Valley and on the southern front, in escort and observation missions. The Air Force of São Paulo was under the overall command of Major Ivo Borges, Commander of the Aviation Units of the Constitutionalist Aviation, and Major Lysias A. Rodrigues, Commander of the Constitutionalist Aviation
