Another place where airships might be useful for transportation is Africa. Lots of resources that need to be moved around, (mostly) terrible road and rail infrastructure. And there the airships wouldn't have to be very high-tech to be safer than road transport. The cost of helium presents a problem, though. Hydrogen is cheaper and provides more lift, but is combustible. http://www.airships.net/helium-hydrogen-airships http://www.airships.net/helium-hydrogen-airships
