During a briefing session by FLIGHT Glynn Lunney on the Black Team shift immediately following the accident, off-duty CONTROL Bob Carlton joins the conversation to give the MOCR flight controllers, and not incidentally Glynn himself, the straight talk on just how austere a power/water profile they will need to adhere to in order to get the crew home safely. This chilling opening dialogue really drives home just how grim the situation was:
CONTROL: Glenn, the guys in the back are running this water profile. Right now it looks like it's coming in real tight, the water itself.
FLIGHT: Yeah? Assuming we stay at this level from now on?
CONTROL: Negative. Assuming we power down post PC2.
