Greener and cheaper death from the skies.

Thanks to those tree-huggers in the United States Air Force, civilization-ending nuclear winter can now be delivered by a more environmentally friendly strategic supersonic bomber.

This week, the Air Force successfully completed a supersonic flight of a B-1 Lancer bomber using a fuel that is less dependent on foreign oil, less expensive and "greener" to boot.

Using a 50% petroleum and 50% synthetic fuel derived from natural gas, Armageddon can now be delivered at a cost savings of between $30 and $50 per barrel over its 100% petroleum counterpart.
