Are there any ways to lock down ships on the upper landing pad to prevent them from taking off (let's say someone wants to escape)? On the same topic, is there a way to forcibly detach a ship if it's an unwanted visitor?

We don't have any specific details to discuss regarding the topic of security and potential griefing and how it interacts with this ship and other similar ones. But, both the scenarios listed here are areas we are discussing internally, particularly how we wish to deal with them using the current and planned range of mechanics.
