- Cadet Happy: I've got it plotted, sir. You want to check my figures?
- Cmdr. Buzz Corry: Your astragation has been on the mark lately, Happy. I'll take your word for it.
- Cadet Happy: Well, thank you, sir. We're at 10,000 BEUs from Major Robertson's position right now, sir, and if we correct three degrees starboard and maintain our present speed, we'll intersect Major Robertson's vector on a line of relative motion in 34 minutes.
- Cmdr. Buzz Corry: Got it... Are you sure that's right?
- Cadet Happy: Oh, yes sir. Absolutely, sir. I'd stake my reputation on it... I think.
- Maj. Robbie Robertson: Seems that Redrow is self-conscious. He doesn't want me looking over his shoulder. He's changing vector.
- Cmdr. Buzz Corry: Where's he headed now?
- Maj. Robbie Robertson: For Mars. If he keeps on this vector it looks like he'll wind up on the top side of the Red Planet.
- Cmdr. Buzz Corry: In the ice cap?
- Maj. Robbie Robertson: Yeah. Fine thing, too - me without my red flannels.
- Ed Redrow: That's the secret of my success, Billy boy, to always cover up my tracks... and then I stick around to see that nobody *uncovers* 'em.
- Cadet Happy: Smokin' rockets! We're 50 miles from Colfax, no ship, no communication and we're stranded right in the middle of the ice desert.
- Cmdr. Buzz Corry: And Robbie's still missing.
- Ed Redrow: No, Billy boy, no guns. Just let nature do our work for us - and it will. Just give it time.

- Cadet Happy: Well, Major Robertson seems to be resting easily.
- Cmdr. Buzz Corry: Oh, he's all right. We'll have him in a hospital bed in a few minutes.
- Maj. Robbie Robertson: Hospital bed? Oh no, not me!
- Cadet Happy: Commander, did you hear what I heard?
- Cmdr. Buzz Corry: Now, I know he's going to be all right. He's feeling well enough already to argue.
- Cadet Happy: Smokin' rockets, what a constitution!
- Maj. Robbie Robertson: It's not my constitution, Hap. Confidentially, I did have on my red flannels.
