Can we see the apocalypse coming by tracking billionaires’ jets?

They have endless amounts of money. Sophisticated bunkers. Private jets. Might the oligarchs of the world know — or be warned — in advance of a nuclear apocalypse?

So goes the theory underpinning the newest project from Los Angeles artist and coder Kyle McDonald, who has created what he calls an Apocalypse Early Warning System by tracking private jets around the world. If a large number of jets suddenly flee city centers, transporting their likely affluent passengers to bunkers and isolated resorts, he figures it might be a warning sign for the rest of us.
