The theory of flight has not changed. The propeller airplanes of the 1900's, World War one and World War Two pushed the plane forward against air molecules; quite similar to using sails to propel you forward.

The theory of flight has not changed.  The propeller airplanes of the 1900's, World War one and World War Two pushed the plane forward against air molecules; quite similar to using sails to propel you forward.   You generate enough speed in the turbine with the engine to reach mach speeds while respecting the dynamics of drag and lift to overcome the inertia of gravity.    You could put an engine like that in a KIA Stinger; beautiful!  You could use any fuel to run the turbine or engine that drives the propeller.   If you look at a modern jet engine, the truth is that it is also a turbine propelling the plane forward.  It has little to do with the fuel since you could design a jet engine to run on diesel, kerosene or liquid hydrogen.  Liquid hydrogen is sometimes used for military applications since it is less flammable and also more efficient so that you would have to spend less time refueling and this gives the planes more range for bombing missions.  The drones are powered by hydrogen fuel cells and can be in the air for ten hours or more.  


So, there is no doubt that you could retrofit an old ox cart fighter bomber.  You have about 30 of them sitting in a warehouse and  they could be used to address hotspots around the world.
