One of the greatest hurdles for major construction in remote areas is moving heavy building materials to the worksite. Road-building is an environmental issue, as well as often being cost-prohibitive and impossible in many terrains. Some areas are unreachable by cargo ship, large cargo planes require good weather and long runways, and helicopters simply can't carry heavy enough loads - which is why Skyhook's Jess Heavy Lifter is so significant. It combines the neutral buoyancy and stability of an airship with the lifting power of four big rotors. Capable of lifting 40 tons (80,000lbs) vertically and transporting the load more than 200 miles without refuelling, the JHL-40 offers twice the load capacity of the world's current largest cargo helicopter.
