Doomsday Plane.
OK. Doomsday scenario's. ELE's, extinction level events.
Asteroid/meteor strike. A plane can take you away from the impact zone and take you somewhere safer in the short term, but you're going to have to land somewhere and deal with it. Then you need a Doomsday bunker.
All out Thermonuclear war. A plane can take you to a safer, non targeted place, but you're going to have to land eventually. Then you need a Doomsday bunker.
Global pandemic. A plane can take you to a place that isn't infectious yet, but then you need a Doomsday bunker. (With good air filtration).
Lithospheric decoupling. A plane can provide temporary respite from the geological chaos on the surface and avoid the supersonic winds as the "earth stands still", but you're going to have to have the range and endurance to get to somewhere less impacted so you can land. Then you're going to need a Doomsday bunker to weather the months or years of volcanic ash fall, geologic "nuclear" winter, and the inevitable famine that will ensue.
Looks to me like the Doomsday plane is just part of the equation for Continuation of Government/Continuation of Civilization.
So, are there Doomsday bunkers scattered about the earth?
