- [after listening to the Army's surveying of the Sidewinder crash]
- Jeff Tracy: [to John] I think this frequency should be put on priority monitoring. The situation could get pretty desperate.
- Scott Tracy: Why don't I shoot out there, Father - see if they want any help? It wouldn't take long.
- Jeff Tracy: No, Scott - we can't go shoving our noses into this uninvited. For all we know, the Army might be engaged in a top-secret operation. John?
- John Tracy: Yes, Father?
- Jeff Tracy: John, I want you to keep this frequency clear. Down here I'm going to put Scott on emergency standby.
- John Tracy: F-A-B, Father.
- Jeff Tracy: All right, Scott. Get down to Thunderbird 1 and get her ready for launching.
- Scott Tracy: I'm on my way.
- Jeff Tracy: If the Army decide they want our help, we don't want to keep them waiting a minute longer than necessary.
- Lieutenant Ralph: There's only one thing left to do, General. I'll go down there and try again.
- General Peters: I don't like it, Ralph. Two brave men have been badly injured in that pit. I don't know if I should risk another life.
- Lieutenant Ralph: [insistently] But we must keep trying, General. There are three men trapped down there.
- General Peters: [in despair] If only we weren't so darned far from civilization, We'd stand a remote chance of effecting a rescue, but...
- Lieutenant Ralph: [interrupting] "Rescue"? You said "Rescue", General. That's the answer. Yeah, that's the answer!
