Quote context

[...]

- Perhaps our best move would be to attempt an attack on the Moon.

- We'd be at a terrific disadvantage. I don't even see how we could land ships there in face of their ray guns.

- But we just can't sit here and wait to be attacked.

- No, of course not.

- Retik the Ruler told me they plan to attack after their saboteurs here have accomplished their mission.

- If we could round up the gang operating here, we may stave off the attack until we are better prepared to meet it.

- Yes, that's certainly the first thing to do.

- You know some of the saboteurs don't you?

- Yes, well, that is by sight.

- And my flying suit gives me a considerable advantage in running them down.

- Right.

- I'll have you notified whenever there's another attack.

- In the meantime we'll put every available man on this case.

- Goodbye Cody.

- Goodbye sir.
