To the untrained eye there’s nothing remarkable about the A44 autobahn in central Germany, the motorway that links the industrial and heavily-populated Rhine-Ruhr region to the country’s heartland.
But just near to the small town of Buren the road, ever so subtly, begins to change to serve its secret — and chilling — second purpose.
At this spot, the A44 doubles up as a secret military runway ready and waiting for war to be declared.
