A B-52 Buffalo flies overhead at Edwards Air Force Base in the Mojave Desert burning alternative fuel from the number seven and eight engines in the far right wing pod. I took the photo in 2005 or 2006 when the Air Force was pressing hard to use alternative or bio fuels. In this case the fuel was made from gas following a process developed in South Africa and originally produced in Germany. The black stream of the Jet A is reduced from those pods.
