Inside the <Denver> airport you will find very strange disturbing paintings. A place where you would think the designers would choose calming images as nervous travellers board airplanes.

Instead the sculptures and paintings show the end of the world, people living in basements, refugees above ground, and a man with an eagle and a AK47 killing the dove of peace. Burning bushes and people in coffins.

The art shows the true purpose of Denver International airport. An underground shelter to escape what is depicted in the paintings. The end of the world.

Phil Schneider is an engineer who had been involved for many years working in construction for the Industrial Defense Complex building giant “Deep Underground Bases.” He told me that he had been offered the position of head engineer for the construction of the base that was to go under the new Denver International Airport back in the early 80s.

I will tell you this–it is strange down there under Denver Airport. This airport underground puts out a set of feelings. I can’t tell you if what I am picking up there are things that are going on underground in that area at this time, or if I am picking up what has happened there in the future which we have not arrived at yet.

Schneider said the [plans] for the complex were for hundreds of miles of underground roads, all connecting with high-speed bullet trains that can go at “Mach” speeds. He also went on to tell me that most of these bases are now jointly occupied by humans and either ancient earth races or alien races. According to him, these underground bases are to serve many different purposes, such as medical research labs, prisons, work camps, military accommodations, food storage, etc.
