Wouldn't shooting down one of these constitute attacking a comercial aircraft of american origin? I think the implications of that would rule out organized military or other very well-financed organizations unless they are run by lunatics. But I've never attacked commercial us aircraft, so if anyone has experience with it...

Unlike satellites the airspace where the blimp would fly would be in the territorial area of the country in question so they would have every right to make it turn away or force it down.

Of course the warlords who might actually control some parts of these countries wouldn't have that ability nor would they care about shooting it down.
