Conceptual artist and researcher Mark McCandlish discussed unusual and secretive technologies related to aircraft and UFOs. He first became exposed to experimental and clandestine projects while creating technical illustrations for aerospace companies such as Lockheed. One such vehicle, which later became known as the Aurora, could travel at speeds up to 17,000 mph, he estimated, and made use of three different propulsion systems.
Many of the triangular sightings, such as seen across United States, have a terrestrial source– the U.S. military, said McCandlish.
