Yes, I would say so. There are ISO liquid transport systems with a container that can carry close to 30 tonnes. They can transport liquid gas, while respecting the standards for transporting dangerous goods. For transporting untreated materials, even if it's something worth $3 per cubic metre, our market studies show that air transport is not cost effective if there are no other options for delivering the product. It would be better to use roads or waterways.
