Letter from Miguel Angel Garcia Macias regarding Stratospheric Aerostats
Translated letter from a self-described pianist and inventor in Veracruz discussing his theories about 'stratospheric aerostats' (flying saucers) using atomic force.
A self-described "Pianist, Composer, Discoverer and Ideographic Inventor" from Veracruz wrote to what he thought was America's flying saucer commission in March 1950. Miguel Angel Garcia Macias believed the U.S. was building stratospheric aerostats powered by atomic force, and he had designs for something similar -- vehicles of "Conic-Global" form that could move through water and air at velocities "comparable only with THOUGHT." He included engineering-style schematics of propulsion systems and stability mechanisms. The FBI filed it. Also in the package: a Mexican newspaper article featuring photographs of an object at 8,000-9,000 feet over Durango, taken by engineering student German Horacio Robles Jr. The object appeared as a "double truncated cone, joined at bases."
- Garcia Macias believed the US was developing stratospheric aerostats using atomic force
- He described apparatus using "Conic-Global" form that could move through water and air with velocity "comparable only with THOUGHT"
- Propulsion described as nuclear-atomic force applied through stratospheric skyrockets
- German Horacio Robles Jr., an engineering student, photographed an object at 8,000-9,000 feet over Durango
- The photographed object appeared as a "double truncated cone, joined at bases"
- Garcia Macias proposed the apparatus could be used to "avoid Atomic Explosion on the Earth"
- Multiple detailed engineering-style schematics accompanied the correspondence
- The newspaper article was published March 16, 1950 (Numero 12,098)
