There was a lot of development in this type of transport in World War I and World War II. It used hydrogen and was very dangerous. We all remember the zeppelins that caught fire in New York. Well, we don't remember it, but we've seen it. It's big, it's huge. Of course, we need to make people safe because an accident would have enormous consequences. But what you can do is go and find all the cargo with a boat.
The engine isn't small, so where there is space, could you really land it anywhere, on water or on various kinds of terrain?
