This is an awesome concept for a hybrid airship used for freighting. Theres some really amazing buoyancy/ballast technology out there that could make airfreight the new means by which to transport goods. It's not like these things are slow either. Some of these guys reckon their airship/glider combo deal can glide at up to 200 mph!

The future of freight according to Rob, Chris and Luke....ENJOY!
