A dirigible is a vehicle operating in a fluid environment. As with ships (fluid is a liquid in this case), the rudder produces drag as well as directional control. It is desirable to keep the drag inducing devices to the aft not only for reasons of visibility, but also for reasons of kinetic enegy. A rudder input on the front, along with inertia from the weight of the dirigible, may cause control problems. Imagine riding a motorcyle that only had front brakes (drag). The inertia from the weight of the bike may put the bike into a spin (a loss of or less effective control condition). Since a rudder is a flight control, usable only with air flowing over it, you really have take into consideration the weight and speed of the craft.
Steerable thrust, like ducted fans, are far better than a flight control surface when it comes to dirigibles.

Because, if the rudder is in the front, as you turn the rudder wants to stay in the direction of the turn and it is hard to overcome do to hydrodynamic forces. With the rudder in the rear you do not have to fight it as it wants to automatically center itself.

Aero/hydrodynamics: the same reason boats have rudder in the back, and airplanes have control surfaces in the tail: it works BETTER that way.

the Hindenburg was a hot airbag that blew up real good ..rush is not trying to make friends .. he's not trying to have the most coherent thoughts .. he's not trying to shape a nations conscience .. what he is interested in is ratings ,, getting and keeping your attention and keeping his name on your lips .. love or hate he doesn't care because it's an act for cash .. ever watch jerry springer .. do you think he really thought the little monologue at the end of his show was gonna change lives .. na ..!! keep the ratings up and cash the checks

Any control surface located ahead of the center of aerodynamic pressure (which in most cases is pretty much were the center of gravity is located) is destabilizing.
