These primitive dirigibles are lofted high by hot air inflating huge bags of sewn rackoxen, iguanodon or sandworm gut (the most highly prized material). Air is heated by burning compressed bio-methane gas. Propulsion is provided by electric or alcohol-powered props of limited power. Airships are mostly restricted to traveling with the seasonal winds (north in winter, south in summer), across the wind, or directly into a light headwind under 25kph. Some few airships with powerful engines can make way in 30kph headwind (5-6kph net airspeed). Piloting and maintaining these cranky contraptions has been refined to a rare and almost magical art form over the decades. Occasionally an airship is blown far afield or lost to high winds, sandstorms or rad-storms.
