A flight dynamics assistant during the Gold team shift just prior to re-entry at 123:11 GET calls up FIDO Bill Stoval essentially to ask if he can go home early due to fatigue. He had been off his game all night, including a really serious blunder earlier in the evening that resulted in GUIDO Bales and RETRO Spencer arguing over whether a REFSMMAT stored in the RTCC was the same one as earlier in the morning. It had been stored incorrectly.
Amidst all of the technical jargon on the FIDO loop, clips like these really show the human impact that the Apollo 13 incident had on the flight controllers who were trying to manage the situation on the ground, many of them not getting enough sleep or just outright pulling all-nighters.
