Mexico City (Mexico, D.F.), Mexico

On March 19, 1950, Miguel Angel Garcia Macias, a self-described Ideographic Inventor from Veracruz, Mexico, wrote to the President of the Commission of Scientific Investigation of the United States of North America in New York, describing "stratospheric aerostats" in a Conic-Global form using Nuclear-Atomic force. The letter was received by the FBI New York Field Office on April 7, 1950, and translated by Mrs. Sophia Saliba.
