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 other plans for similar situations, where crews are alive but in a situation that cannot be recovered, exist? Both modern and historical examples are of interest.
Specifically I'm asking about how the situation would be handled, what the crew might do, what the ground staff might do, what statements might be made public etc. Anything related to the handling of it, including covering it up.
