There is some talk out there of hollow poles on the Earth. One theory says that the North pole has a large hole that allows the inner-Earth residents UFO’s to fly in and out… However looking at some amateur satellite images captured from NOAA satellites, this is not the case. Have a look at these images from a Ham radio operator in Vasa, Finland. These are images of the extreme Northern latitude including the North Pole: no hole is to be seen. To be neutral on the subject, there is always cloud cover – however there are also thermal images.
