He talks of "machines" under the surface of Mars !
Here is a quote from him:
“There are structures on the surface of Mars. I will tell you for the record that there are structures underneath the surface of Mars that cannot be seen by the Voyager cameras that went by in 1976. I will also tell you that there are machines on the surface of Mars and there are machines under the surface of Mars that you can look at, you can find out in detail, you can see what they are, where they are, who they are and a lot of detail about them.”
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
