ответ:People are searching for a 'greener' for of air transport. Some experts think large balloons that can carry people, called 'airships', are a solution. Here are some recent predictions:
- Airships land and take off straight up from the ground, so they
will carry people and things to places with no airports, like the Arctic.
- They are comfortable and quiet so airships
will be probably popular for luxury travel.
- Airships can carry things across short distances, so they
will transport cars across rivers, like ferries.
- They can only carry 12 people, so trips
won't be probably cheap.
