A SOMEWHAT CARELESS REPETITION)
These were found resting in the lower astral by a predatory race of another galaxy.
The story of how they were dealt with is of some interest. They were swept into intergalactic space in isolation to ensure there would be no damage in their destruction. A mighty Cosmic Being faced them and drew their combined power against himself as a demonstration of his power and indestructability.
The crews of two were transferred into the third ship, installed with a system to broadcast a warning against any more intrusion this galaxy, in such a way impossible to delete and sent it home.
He then destroyed the other two in a flare of power into the energy of atomic structure, which must have been something like a huge atomic bomb blast.
I was told the crews were Android soldiers capable of fighting in space, independent of any kind of sustenance designed only to kill.
