Its the totality of chaos, a volcano eruption on Iceland have paralyzed ALL airtraffic throughout northern europe. Its dark clouds travel with immense speed towards Norway. Volcanoes are a much-feared peril in civil aviation, disgorging fine ash that can damage jet engines, choke the hi-tech probes used in modern avionics and scour a plane's windscreen to the point of invisibility
Its uncertain when the planes once again can be back in the air, its the butterflyeffect, the mother of CHAOSTHEORY!
