The abandoned city is Camp Century, a military installation constructed in 1959 by connecting a network of tunnels beneath a near-surface layer of the Greenland ice sheet.
The mystery around this tropical base has more to do with the dodgy way the UK and US manage to steal the island from the locals and less about what occurs there.
Whatever was happening at the base, people from the local villages say they have known about the training grounds for a while now, and report that the soldiers/security guards roamed around the nearby villages in groups, harassing people and ‘behaving in an almost arrogant manner’.
After weeks of searching, there is still no sign of the MH370 wreckage. All that the extensive search for MH370 has found is some floating trash in the Indian Ocean. So what’s up? Take a look at this theory by a YouTube user, Montagraph. He suspects flight MH370 is being held at a military airbase.
