<!-- Hawker Hunter GA11-->

<!--  This is as near as an authentic representation of the aircraft as I can make 
      it. The numbers closely match those of the original aircraft, except for the 
	  location of some of the masses, which have been adjusted to make the model fly 
	  correctly.

	  Ver 0.1.2  2005/01/24 - add a working arrester hook - WARNING the Hunter only used the 
	             hook on wire-equipped Royal Naval Air Stations. It is not equipped with a 
				 catapult launch mechanism. You can land on a carrier, but you can't take 
				 off again.
