When Obi wan and qui gon went on the trade fed. c-9979 transports down to Naboo, how did they breathe? Was there oxygen inside the transports? Cause I was reading in the complete cross sections book and it said that is was fully operated by droids. So there's no reason for air. There needs to be gravity and stuff but no air, let alone breathable oxygen... Did they use the oxygen breather masks that they used when going to the underwater Gungan city?
