Not like you can simply order a dirigible online. Unless he built his own, not even sure where one would get such a thing. And if building your own, where the hell would you get/store the helium gas (and how much would that cost)? Then, you have to have gas or some other fuel for the turbines to actually steer and move once aloft. Seems unlikely. For the same or less money, could likely just get a used small airplane.
I'm actually surprised dirigibles aren't more widely used by the military, especially as drones. Takes a lot to shoot one down with regular arms fire. I imagine they'd have a big radar cross-section, even drones, but still, with today's stealth materials and all, seems like at least a good solution for a low-tech threat (such as terrorist camps).
