Mark was in the US Air Force for a time, and then, near as I can gather, he became an illustrator for aerospace tech. Mark has worked for some of the major aerospace corporations in the United States.
His colleague, Brad Sorenson, with whom he studied and mentions in the video, has been inside a facility at Norton Air Force Base, where he witnessed 3 different-sized alien reproduction vehicles, or ARVs, that were fully operational and hovering.
In this incredibly detailed testimony, you will learn that the US not only has operational antigravity propulsion devices, but we have had them for many, many years and they have been developed through the study, in part, of extraterrestrial vehicles over the past fifty years. In addition, we have the drawing from aerospace inventor Brad Sorenson of the devices that he saw, as well as a schematic of one of these alien reproduction vehicles – in high resolution, with remarkable detail.
In this video, Mark talks non-stop, authoritatively, never missing a beat about a number of things that will blow your mind: saucers at an Air Force base; propulsion systems based on Townsend Brown and Nikolai Tesla’s ideas, and patents related to the technology, eyewitness sightings of soundless craft which could move at multiple times the speed of sound without causing shockwaves… and so much other information. This is an interview done by Dr. Greer for the Sirius Disclosure project.
Highly recommended video with heaps of technical information.
