The US Air Force and Navy appear to have been in an unspoken competition over their use of “green” or synthetic alternative fuels in their fighters — each vying for “firsts.”

It appears the Air Force Thunderbirds beat the Navy Blue Angels to be the first to use it in their demonstration team:

The Thunderbirds will use alternative fuel, unprecedented for any Department of Defense aerial team, at the [airshow] here May 20 and 21, officials said.

The team will fly with Camelina-based hydrotreated renewable jet fuel as part of the nation’s overall strategy to reduce reliance on foreign energy and establish greater energy security through conservation and use of “home grown” alternative energy sources, said Terry Yonkers, the assistant secretary of the Air Force for installations, environment and logistics.

On a related noted, the Blue Angels apparently had an ‘incident’ at a recent event and have cancelled their traditional airshow preceding the USNA graduation.  No word yet on whether they will cancel their fly-over for the graduation itself.  (The Thunderbirds perform a show at the graduation itself.)
