The US Navy has been granted a patent for an advanced aircraft which resembles a flying saucer UFO. [...]
The patent is highly complex and describes methods of reducing the mass of an aircraft using various techniques including the generation of gravity waves, which were first detected in 2016 after being produced when two black holes collided.https://metro.co.uk/2019/04/18/us-navy-secretly-designed-super-fast-futuristic-aircraft-resembling-ufo-documents-reveal-9246755/

In other words, if you can a) create a room temperature superconductor capable of storing an incredibly high amount of energy and b) get the energy field created by that superconductor moving at incredibly high speeds around or within the craft, you can create a polarized energy vacuum around it which allows it to basically ignore the energy of the air or water around it, thereby removing its own inertia and mass from the equation.
