Care to answer the question though?
It is still entirely valid.
To put it in another light, had I dominion over the entirety of mankind, I would crash gently such a vessel in shallow water if possible.
The nature of the alien life would not be probed in the sense of psychology, the termination protocols would not be enacted, the removal of the alien lives from Earth would take place, they would be returned to flight at my earliest opportunity.. Data would be gathered and they would be told not to return.
Or they would be obliterated in an instant.. with zero question. I would pick through the wreckage and expect that I had now made an enemy who would do the same to me, for eternity, perhaps even disallowing my fleet to travel across light years of potential journey direction in increasing conal relevance.
I would be expected in a non hostile species to avoid outflanking their home world for a journey.
If layer x of material is isolated in magnitude at point z in space, how can we acquire the load to take home if we have an enemy?.
