Well apparently Airships are going to get a second try in 2013. A Ukrainian entrepreneur Igor Pasternak claims to have solved the buoyancy problem which has long prevented the usefulness of airships. What happens is that when the airship uses up its fuel or when its cargo is dropped, it lightens the airship and then you have to vent in very costly helium in order to return it to earth. Without a way to control buoyancy, the take-offs and landings become complicated. Pasternak claims to have settled this issue by compressing the pricey gas so you can conserve it for later use. The Defense Department has given him the contract to provide them with a working demonstration by 2013. Called the Pelican, the airship will fly without any payload at first but if this thing works, we might be looking at a new Era of Airships."
