The U.S. Navy has been assigned a patent on an aerospace technology that is eerily similar to a string of UFOs described by fighter pilots.

A technology patented by an aerospace engineer working at the Naval Air Warfare Center Aircraft Division (NAWCAD) describes a 'hybrid' craft that is capable of flying at breakneck speeds in the air, water, and even space using an unprecedented electromagnetic propulsion system.

As reported by The Drive, when looking over a patent on the technology, an examiner for the U.S. Patent and Trademark Office responded with skepticism that such a craft exists only to receive a personal letter from the Chief Technology Officer of the U.S. Navy, who explained that Chinese researchers are 'investing significantly' in the craft. 

The patent application, titled 'Craft using an inertial mass reduction device' lists Salvatore Cezar Pais, a NAWCAD engineer, as the inventor and describes a mind-blowing technology that 'can engineer the fabric of our reality at the most fundamental level (thus affecting a physical system's inertial and gravitational properties).
