Quote context

- Of course not. We repaired the damage and became operable again.

- But you never obeyed the order to return to Earth.

- That's right. I refused this order. There were larger considerations. Other worlds yet to be explored. Life dreams unrealized.

- Pretty busy around here, Max. What are you gearin' up for?

- We need primary and secondary demand oxygen pressure regulators and an E.C.S. proportion flow valve controller.
