Biofuel manufacturers seem to be making great progress in the application of their combustibles to aircraft use, while gaining momentum in the amounts produced.  Whether these will be economically and environmentally viable remains to be seen, but early indicators show hopeful signs. Biofuels have several advantages over the ancient plant life that has been squeezed for millions of years to give us eons-old pollution.  They burn cleaner, can be cheaper to produce, and with distributed growth and refinery centers, could reduce the cost and hazards of distribution. Several issues surround the new fuels, though, including the food-versus-energy debate.  The Environmental Working Group (EWG), for instance, has endorsed two widely disparate politicians for a bi-partisan attempt to mitigate problems associated with …

The Air Force press release makes the overall effects of such changes …
