Well.. not the real name yet xD But yes. Soon, after some tests we will have a flying version of the caravan. But it wont suffer from the land issues since it can fly over anything. A heavily altered trits-whale hybrid with mechanical parts to allow carrying goods inside and also be lighter than air. We still don't know if its more machine or more creature, you sure pushed the limits in that integration.
It will works like the caravan, will pick and deliver huge amounts (cargo train size) of items between the points (hopefully not bringing it back). It can be used to transport big amounts of materials without relay on trails or zones with no limits for distance. But also wont be as programable as trains for example. Can be very useful in some setups.
