Section 2 is an area of the underground facility on Altair. Shortly after the android SG-1 returned to Altair after they had almost ran out of power back at Stargate Command a robotic voice announce that there was a coolant leak in the secondary coils and immediate attention was required. Harlan stated this was in Section 2 and went to go and fix it, leaving the robotic SG-1 behind to rest and re-gain their power. The android Jack then went and talked to Harlan in section 2 while he was repairing the leak. Harlan then told them the story of the Altairans until it was announced that there was another coolant leak which would affect the main power source. (SG1: "Tin Man")
