RE: synfuel supplier for Air Force, Wiki provides part of the answer:

In Dec. 2007, Rentech hired lobbying firm Brownstein Hyatt & Farber, which will lobby the federal government to fund coal-to-liquids development. Also in December, Rentech appointed Dr. Ronald Sega to its board of directors. Sega headed the Air Force’s energy strategy, and flew on the first Air Force jet powered by synthetic fuels in September 2006.

Still curious if the Air Force is developing it’s own proprietary synfuel process.
