Vladimir Putin has a 'Flying Kremlin' plane in case things go very wrong.
As Cillian Murphy's character in 28 Days Later said, 'there's always a government, they're in a bunker or a plane', and this plane is Putin's place to run Russia from should things go to s**t.
Granted, he's very likely the one who would do the s**t that would cause the end of the world, and the world is taking notice of the next moves the Russian president might make.
In recent weeks EU citizens have been advised to put together a supply bag with enough stuff to keep them going for 72 hours, while an expert told LADbible that having a supply bag was a good idea but in the case of World War Three Brits would be better off making sure they had a supply in their home and hunkering down.
Germany is putting together guidelines on what the country should do if international relations fall apart and conflict in Europe comes to their doorstep.

Should things go badly for Putin then he's got his own private 'doomsday' plane, an Ilyushin Il-80, which Euronews reports has been dubbed the 'Flying Kremlin'.
The aircraft is so named because it's the place Putin and members of his government will go should the worst-case scenario happen and his unprovoked aggression triggers a global catastrophe.
It's designed to provide protection against a nuclear blast, as the plane has no windows besides those in the cockpit, and is packed with special equipment which would allow it to be a hub for command and communication.
Euronews says it even has protection from electromagnetic attacks that would disable the plane as flying command post for Putin.

Russia isn't the only country with these aircraft, the US has a fleet of four 'doomsday planes' like this which they keep in case they need to move officials away from the end of the world.
Seeing these planes in the sky could mean some very bad things.
The US fleet of planes are occasionally used to transport government officials to important events so spotting one doesn't mean the end is nigh.
But if you were to look up to the sky (in Russia, presumably) and see Putin's own 'Flying Kremlin' overhead then you might wonder what he needs it for.
