Google Maps is a fantastic tool when it comes to exploring the world over from the comfort of the living room. However, there are some sites that you can not see on Google. Try to find:

Volkel Air Base, The Netherlands

According to documents issued by Wikileaks, the United States claims that supplies since the Cold War are still there.

Helipuerto de Cartagena, Los Dolores, Spain

There is not much information about this area, which in the foreground looks like there are only empty fields.

Roses, Spain

This is believed to be the base of the 875 aircraft of the US Air Force and the Warning Team.

The National Security Bureau, Taiwan

This is the headquarters of the National Security Bureau of China, the country's leading information gathering organization.

NATO Air Base Geilenkirchen, Germany

Although this base is valid on Google Maps, the image is completely unclear.

US-Mexico border: Hudspeth, Texas, USA

It is about an area located in Texas and is northeast of the Mexican border.

Israel

Although you can see Israeli air images when you are looking for a closer view of buildings, it is very unclear. This happens almost with most of the country in question.
