That means if they are destroyed during the game , they cannot be brought back. They weren't "set aside". A ship outside of the play area is "destroyed". However, if it was "set aside", it triggers the appropriate card (mission or upgrade). It CAN be brought into play through the use of the card.
Where it would remain destroyed, as nowhere does it state that it is not destroyed.
