Why Jet Fuel (and Turbine Engines?)

Every three months we go through this routine -- pumping avgas into 77 drums that get shipped in a container to Cameroon. We have two airplanes and one helicopter there serving a mission hospital and various mission groups, besides our own Wycliffe Bible Translator workers, in a seven country area. All three aircraft burn aviation gasoline -- "avgas" -- which is not easily available in the country. Believe it or not, this is the most economical way to get fuel to our program there, and keep service going to many self-sacrificing workers. Soon we hope we can send our first turbine-powered aircraft and begin the transition to an all-turbine fleet in Cameroon.
Since everyone has airline service around the world, jet fuel is plentiful and relatively cheap.
