Juan Pablo Aldasoro Suárez (1893–1962) and Eduardo Aldasoro Suárez (1894-1968) were aviation pioneers.[1]

Biography[edit]

Juan was born on September 14, 1893 in the "Casa Grande" of Real of Monte, state of Hidalgo, Mexico. Eduardo was born on October 27, 1894. Their father was Andrés Aldasoro, Minister of Promotion under Porfirio Díaz and was general manager of the "Las Dos Estrellas" mine in the state of Michoacán.

The inseparable brothers alternated their studies of preparatory with their vocation being mechanics and a passion for flying, and through publications and magazines of those days time they inquired researched about everything related to aviation.

Aircraft builders[edit]

By 1908 they began to design and construct their first gliders, which were tested on fields near the Piedad Cemetery (Panteón de la Piedad, now Avenida Cuauhtémoc in Mexico City). They achieved brilliant results as they managed to fly about one hundred meters in their own designed gliders.

They used diverse methods for the propulsion: the glider was towed by a steam automobile that reached a terminal velocity of 50 km/hour. The structure of the plane was made of wood, the wings were covered by a blanket hardened with engrudo and the landing gear was adapted from steel tubes and bicycle wheels. The gliders were cautiously hidden, to avoid someone else stealing their design by covering them with linen cloths.

The tests were performed at different hours, mainly at dawn. For his first flights he used leader mandiles for protection, since the gliders were severely damaged after each flight.

First flights[edit]

March 9, 1909 was a very important day for the Aldasoro brothers; that day they took the glider towards the outskirts of Mexico City, nowadays Calle de Querétaro in Colonia Roma. This was the first street to be opened in the neighbourhood and for them it represented a nice track without obstacles. They tied the glider to a steam car called "White", which was the fastest automobile of those days. Juan Pablo would be the pilot and his brother Eduardo would be in charge of driving the car that would tow the glider.

As they started moving, a huge cloud of dust arose, the glider slowly elevated the tail and finally emerged from the cloud. The car continued moving for about 300 meters and then slowly decreased the speed to allow the glider to loosen the cable and then continue flying. Suddenly something unexpected happened. The device to release the cable did not work properly and Juan Pablo went flying above the car without being able to free himself. As the plane continued, the cable pulled it back and immediately turned in a somersault and crashed. The glider was destroyed and, miraculously, Juan Pablo was alive with only a fractured leg. The experience drawn from this flight was extraordinary, the pilot had managed to have absolute control of the glider for more than 480 meters as well as a very stable flight at a height of 10 meters.

This accident and others undergone by Eduardo, did not discouraged them at all. On the contrary, having seen that their planes were able to fly, they decided to construct an engine that could be adapted into an aeroplane. With this intention in mind, they travelled to the mine of "Las Dos Estrellas", in Tlalpujahua, Michoacán, where his father was the manager. They took with them drafts and designs and used the mine's welding and smelting facilities to construct an internal combustion engine with two opposite cylinders. At that time, the existing engines were very heavy and voluminous, they had enormous radiators for cooling, and many of accessories that did not satisfy the required characteristics to propel an aeroplane.

Finally, in January 1911 they finished the construction and testing of the motor, cooled by air, it could develop 60 h.p., and up to 900 RPM. The prime feature was its weight/power ratio: 3 kilos per hp.

In addition, the Aldasoro brothers constructed a very rudimentary wind tunnel to help them study the process of flying. They experimented with different shapes and angles for the wings as well as their centre of gravity. Years before other European designers, they designed the "thick wing", which was highly efficient. They had improved aerodynamics of the airplane. Once assembled all the components, the aeroplane complete with engine was ready to be tested.

Higher calling[edit]

Newspaper article from February 1913 describing the arrival of the Aldasoro Brothers at the Moisant Aviation School

When the aeroplane was finished, President Francisco I. Madero's War Minister General Angel García Peña, inspected the plane very carefully. He decided that before testing it, Juan Pablo and Eduardo Aldasoro should be granted a scholarship by the Government of Mexico to attend the Moisant aviation school in New York. The President of Mexico, Don Francisco I. Madero, was a progressive and visionary man, he thought that aviation offered great possibilities to create a modern army, about which the vocation, the professional formation and a pure patriotic spirit of youth, served as incentive to renew people, styles and customs of the past. Then, the Aldasoro brothers, accompanied by Alberto Salinas Carranza, Gustavo Salinas Camiña and Horacio Ruiz, travelled to the USA and were the first Mexicans to graduate as pilots on March 12, 1913.

The Fédération Aéronautique Internationale granted the licenses nbr. 217 to Juan Pablo Aldasoro and nbr. 218 to Eduardo Aldasoro. On the graduation day, the authorities authorised one of the recent pilots to fly over the Statue of Liberty.

Juan Pablo won the draw and took off the training fields at Long Island NY, he completed the flight, above the waters with total control and security, he reached the Statue, and returned to the fields as the first man to fly over this famous New York symbol. Newspapers and magazines recorded the event with great detail. The New York Council granted a diploma to Juan Pablo Aldasoro in memory of the event and the airplane's propeller is now kept in the National Air and Space Museum in Washington, D.C, where it pays tribute to these pilots who contributed with courage and sacrifice to the history of aviation.

Early Birds[edit]

As Juan Pablo and Eduardo Aldasoro flew "solo" before 1916, they are recognized as part of the Early Birds of Aviation.

President Madero did not have the opportunity to see his dream fulfilled, but those five pioneers, Juan Pablo and Eduardo Aldasoro, Alberto and Gustavo Salinas and Horacio Ruiz, would become the pillars of the Mexican Air Force, not only as founders, but also teachers for the next generation of pilots. The Department of Military Aeronautics, the School, the National Factories of Aeronautical Constructions and the Mexican Air Force, regarded them as pillars and guides. In these institutions they committed their lives and work.

Deaths[edit]

Juan Pablo Aldasoro Suárez died on October 4, 1962 with the rank of Lieutenant Colonel Flying Pilot.

Eduardo Aldasoro Suárez died on November 10, 1968, with the rank of General Brigadier Flying Pilot.

Legacy[edit]

Two bases of the Mexican Air Force were named after the Aldasoro Brothers:

  • Military Air Base Number 4 in Cozumel, Quintana Roo is called General Eduardo Aldasoro Suarez
  • Military Air Base Number 11 in Mexico City is called Teniente Coronel Juan Pablo Aldasoro Suarez

Presence in Literary Works[edit]

Five Mexican pilots that attended the Moissant School of aviation. From Left: Alberto Salinas Carranza, Gustavo Salinas Camiña, Juan Pablo Aldasoro Suárez, Horacio Ruiz Gaviño, Eduardo Aldasoro Suárez.

Carlos Noriega Hope wrote a short story El Tesoro de Cabeza de Vaca which was inspired during a visit to Juan Pablo Aldasoro's Hacienda in the State of Jalisco in the 1920s. The Story appeared in the book La inutil Curiosidad later re-printed under the title of Las experiencias de Miss Patsy. Juan Pablo appears as himself in a fictional story of treasure hunts.

Streets and schools[edit]

There is a street in Mexico City in the "Aviación Civil" neighbourhood south of the International Airport of Mexico City. Other famous Mexican (Juan Guillermo Villasana, Horacio Ruiz, Alberto Salinas and Roberto Fierro) and international pilots (Santos Dumont, Roland Garros, Louis Bleriot, Charles Lindebergh, Alberto Braniff, Enrique Farman, Simon Audenaro) have streets in the same neighbourhood.

A primary school near Toluca (Clave 15EJN0622N, Turno MATUTINO) was named "Hermanos Aldasoro".
