87 ly. That bottle had a big enough heat leak so that it main tained pressure itself. As I said, it started venting on the 8th day. We never used the manual heater on the E'.JS o bottle. 2 Lovell As a matter of fact, the prilna.ry o2 helped, rather we util ized the primary o2 to pump up the pressure on the ro o2 sometime in the early pa.rt of the portion of the flight. Borman Yes, we used the crossover valve. When you hit the squib or when you hit the switch to open the solenoids, even though we had been led to believe that i t takes some time for that pressure to build up, it looked to me that it went to about 250 in the FC o bottle almost immediately. It2 went from 100 to 250 almost immediately. I imagine it will come down when we talk about the FC o2 problem.
