Apologies that this is slightly off-topic, but I thought people might be interested to listen to an extended version of the flight director loop during and after the Challenger disaster. This apparently isn't new but I hadn't heard the full recording before, which goes up until the controllers are released from their duties.

(His last mission. Perhaps unsurprisingly, he chose not to return to Mission Control after this.)
Having heard him frequently joking around when calling checkpoints during the Apollo program, I find it almost unbearably poignant to hear him here reminding the GC that they need a checkpoint. Not to mention his words at the end telling controllers not to speak with anyone about what happened.
