Does the mining barge expert package allow alpha clones to fly these ships?
Mining barges are locked ships for alpha clones. Not allowed to undock even if the required skills were learned during some earlier subscribed period of time.
With a purchase from the new expert system, though, an alpha clone may temporarily unlock access to mining barge required skills. Are alpha clones then able to undock a mining barge during the duration of their purchase?
The answer is yes. In this screenshot, the Mining Barge Operations Expert System has a ship unlock tooltip that confirms alpha clones can undock with the ship.
