The President of the United States famously had a speech prepared for the eventuality of the Apollo 11 crew getting stuck on the moon and unable to be rescued.
What plans have been made for how a similar situation be handled by staff on the ground? Doesn't have to be Apollo related, any non-recoverable situation is okay, and any space agency, not just NASA. For example, the Soviets were known to cover up failures of unmanned satellites quite routinely, but it would be more difficult with a manned craft where the crew had a radio transmitter.
Note: This is not a duplicate of this question. "Ground staff" refers to personnel on the ground, not on the vehicle/space station in question. "Crew" refers to people on the vehicle/space station. These are two separate groups.
Furthermore, when I did ask about both in one question, it was put on hold as "too broad".
