Aerospace Engineer / Inventor
Genuine credentialed aerospace engineer with documented Navy and Space Force employment, patents granted by USPTO, and the Sheehy 'operable' certification on file. The physics described remains unverified by public demonstration. His seriousness and the institutional backing for his patents are well-documented.
U.S. Patent 10,144,532 - Craft using an inertial mass reduction device
Filed 2016, granted 2018. Describes a craft that locally reduces its own inertial mass via accelerated vibration of charged surfaces in a high-frequency electromagnetic field, enabling extreme acceleration without inertial penalty.
U.S. Patent 10,135,366 - High frequency gravitational wave generator
Patent describing a device for emitting and detecting high-frequency gravitational waves, with applications cited in propulsion and detection of UAP.
U.S. Patent 10,322,827 - Hybrid aerospace-undersea craft
A craft capable of operating in air, in space, and underwater without redesign - the so-called 'transmedium' capability matching modern UAP encounter reports.
U.S. Patent 10,135,182 - Piezoelectricity-induced room temperature superconductor
Describes a method for inducing superconductivity at room temperature through piezoelectric forcing, prerequisite for the inertial-mass device.

Naval Aviation Enterprise CTO James Sheehy certifies to USPTO that the Pais craft is operable, citing China-competition rationale.
Transitions from Navy to Space Force employment.
“It is the position of the United States that we cannot afford to be second to China.”
