It has become apparent over the hours following the accident that power will be needed from the LM to the CSM in order to carry out crucial maneuvers for the PC+2 abort. Unfortunately, the procedure for doing this is becoming very lengthy, which FLIGHT Glynn Lunney comments on as TELMU gives his report to him.

Earlier, he feuded with EECOM Liebergot about doing extra cryo-stirs. Not surprisingly, he is very audibly frustrated at the lengthening of the LM umbilical procedure.
