The Aeroscraft is a helium-powered airship with a rigid internal frame made from aluminum and carbon fiber currently in development at San Diego-based Aeros Corporation. The project has been in development since 2006 and has received $35 million in funding from the US government. According to Gizmag, the half-size “Dragon Dream” prototype — which measures 266-feet long and 97-feet wide — recently began flight testing. The Aeroscraft works by releasing canisters of pressurized helium to achieve liftoff and repressurizing the helium to lower the airship.
