There is actually an Airworthiness Directive out prohibiting the use of
JP4 in a number of turbine powered aircraft (including the Boeing 737).
If I remember right, it has to do with the fuel controls not liking
the difference in specific gravity of the two different fuels, which
has actually resulted in in-flight flameouts.  JP4 is still available as
far as I know, and JetA is in common use in most civil turbine aircraft.
