The backup crew and some support crew participated in an interesting rescue scenario with 2 astronauts flying to Skylab to take back the crew of 3 onboard Skylab. This would mean 5 astronauts returning to earth in the command module.

I am wondering what happened with the Skylab hardware modules used inside the water tank after the program training came to an end?
Sorry I missed your question Marco. I think the hardware modules are still at Marshall. But I am not sure.
