Volcopter passenger drone test flight.
Well, if it so happened that more people can be able to fit in the next model of drones they produce, I think that people would rather choose helicopters or choppers instead since it would be more practical. But I get your point. It would also be nice to have a model that can fit several people which can be driven from a good distance for rescue operations, that would be a really big help and would mean that less units would be sent to rescues without risking any pilot rescuer. But other than that, I think it wouldn't really that much sense to make those models so I think deep aero will only produce them if someone really ordered a model like so with valid reasons and of course enough dough..
If the drone will produce a drone that might possible have a multiple seats i am sure that they need first to get an approval to the government on where the drones will fly and
if these drones are being permitted it will become another source of transportation just like the helicopters or planes.
