Again,
What's the killer application?
How about this?
So what sort of roles could it perform? While operating costs are extremely low, don’t expect the Airlander 10 (or the larger Airlander 50) to replace 300-seat airliners on transatlantic flights. However, there could be useful niches in aerial sightseeing where this slow, stable flying vehicle could find a market. Indeed, while the Airlander is currently powered by four diesels, HAV say it is already looking at swapping the forward engines for electric powered thrusters. The idea here, says the company, would be to use the rear diesels for take-off, then switch to the forward electric engines for cruise. For zero-emission, silent aerial cruises over natural wonders like the Grand Canyon or African Savannah this could be a green way of seeing the planet – and spark off a new environmentally-friendly aerial tourist industry. Further in the future, it is not too difficult to imagine how solar-panels on the top surface, powering electric motors, could make Airlander even more green.
