> Buoyant has built and flown four prototype airships. The most recent sub-scale ship that went to air is 20 feet long, with airspeeds of up to 35 miles per hour and a payload capacity of 10 pounds, but the ultimate aim is to build an airship that’s capable of delivering up to 650 pounds of cargo at a cruise speed of around 60 miles per hour.

For depot to depot delivery, how does that compare with an 18 wheeler truck with 30,000 lbs carrying capacity going down the road at 60 miles per hour?
