[Narrator]

Down in the underwater city of Euclidea, the Gregory party finds life rather difficult. It wasn't any too pleasant to think that there was little hope of their rescue. But when they actually hear a radio broadcast with their own man Johnson in Los Angeles as the speaker telling the world of their death, then things do look mighty bad. When the Euclideans started their artificial volcanic eruption and caused the rescue fleet to sail away from the position of the magic island, all hope of Rescue was gone. Mrs. Gregory and Joan are resting in their comfortable quarters in the underwater city while Jerry and Captain Bradford have started for the rocket ship laboratories. There the captain is to be allowed to study the construction and operation of these thousand mile an hour Euclidean planes. Jerry and the captain are standing near the doorway to the scientist quarters waiting for their guide.

[Jerry Hall]

I know it's all right to talk here. That girl submarine commander said it was.

[Joan Gregory]

I guess she ought to know.

[Captain Bradford]

Okay, if you say so, Jerry. But it seems funny to be talking so freely out in this big open room after being so careful in our own quarters.

[Joan Gregory]

Well, there's so many funny things in this crazy place that I'm kind of getting used to.

[Captain Bradford]

I'm afraid we'll never really learn to take all this for granted.

[Joan Gregory]

No, I guess not.

[Jerry Hall]

But look here, Captain Bradford, how did

[Joan Gregory]

it happen that old G47 said I could go into the laboratory with you.

[Captain Bradford]

That surprised me too, son. Maybe he thought you'd be more likely to stay out of trouble there.

[Joan Gregory]

Yeah, well, I won't have much chance to do anything they don't like with a room full of scientists watching me.

[Captain Bradford]

And don't try to do anything. You just keep your eyes open and learn all you can about this place. I'll be figuring how to get my instrument case aboard.

[Jerry Hall]

Oh, that small case that looks like

[Joan Gregory]

a ladies overnight case?

[Narrator]

Yep.

[Captain Bradford]

That's just large enough to comfortably hold a pigeon.

[Joan Gregory]

And then one of these times you'll leave the instrument out of the case and have the pigeon in it, huh?

[Captain Bradford]

Right. But don't get impatient about it, Jerry. May Take weeks or months to get that chance.

[Jerry Hall]

Oh, yeah, I know.

[Joan Gregory]

They'll search that instrument case pretty carefully the first time you take it on board.

[Captain Bradford]

Not only the first time, but a good many times. Our hope is that they'll finally get careless about looking at it. And I'll be able to smuggle a homing pigeon aboard a rocket ship for a test run.

[Joan Gregory]

And it'll have to be a long test run to get the pigeon near enough to Los Angeles. So it'll have a chance to get home.

[Captain Bradford]

Yes, I'd like to be within a few hundred miles or even better than that. And I think that can be arranged. G47 is planning a series of night flights right over the principal cities of the United States.

[Jerry Hall]

But, gee, Tex, he'll get caught at that.

[Captain Bradford]

I'm afraid he won't get caught. Those rocket ships are noiseless practically so. And they'll run without lights. I think it'll be altogether too easy to sneak up on Los Angeles, Chicago or New York and cruise around over them. While G47 studies the cities and maps the important points in each.

[Joan Gregory]

Gee, that sounds like they were getting ready for a war.

[Captain Bradford]

They are. A very definite war, though. This will be the most peaceful, noiseless war the world has ever known.

[Jerry Hall]

What do you think they'll do?

[Captain Bradford]

Just a few magnetic bombs in the cities. All traffic, transportation, telephone, electricity, everything will stop. And that will make the country just as helpless as if it was desert.

[Joan Gregory]

And then the Euclideans land and take

[Jerry Hall]

over the country, huh?

[Captain Bradford]

Looks like that's the idea, Jerry. And not only our country. While that's going on in the United States, the same thing will be happening over Europe, Asia, Australia, Africa and South America. If these Euclideans can do as they expect to do, and I think they can, one hour would be long enough for them to take over the control of the entire world.

[Jerry Hall]

Oh, boy. Wouldn't it be swell if we could stop them?

[Captain Bradford]

Yes, it would be, and we'll try it. But don't get too hopeful about the outcome.

[Jerry Hall]

Oh, I know it looks mighty hard, but we can do it.

[Joan Gregory]

Mrs. Gregory's feeling pretty bad about things now. And while Joan's scared of these crazy Euclideans.

[Jerry Hall]

But we'll do it some way.

[Captain Bradford]

I think so too, son. But we've got a long way to go.

[Jerry Hall]

Quiet. Here comes one of the Euclideans. Which one? Well, I can't see yet. It's too dark back under that balcony.

[Captain Bradford]

Well, I suppose we'll be taken to the laboratory now.

[Jerry Hall]

I hope so. Oh, boy. It's our friend, the Girl submarine, commander.

[Captain Bradford]

So it is.

[Joan Gregory]

That means we get a break.

[Commander Cleostra]

I would not advise you to break anything.

[Captain Bradford]

How do you do, Commander?

[Joan Gregory]

Oh, I didn't mean to break anything.

[Jerry Hall]

I meant that you'd give us a good break.

[Commander Cleostra]

Your expressions mean little to me, hall, and I am of the opinion they mean little at all times.

[Jerry Hall]

Oh, is that so?

[Captain Bradford]

Never mind, Jerry. Well, Commander, what are the orders?

[Commander Cleostra]

You, Captain Bradford, and you, hall, will accompany me to the transportation laboratory.

[Jerry Hall]

Oh, boy.

[Joan Gregory]

And will we get a ride in a rocket ship.

[Commander Cleostra]

I have been instructed to make a test flight with you two as passengers.

[Captain Bradford]

Well, we're ready.

[Commander Cleostra]

We will go at once.

[Joan Gregory]

Oh, Jerry. Jerry.

[Jerry Hall]

Hey, there's Joan over there.

[Commander Cleostra]

You will have no time to speak with her.

[Joan Gregory]

Wait a moment, Jerry. I am going with you.

[Commander Cleostra]

You are not.

[Captain Bradford]

Sorry, Joan, but this is a business trip and the commander has orders for only Jerry and myself.

[Jerry Hall]

Hey, commander, couldn't you let Joan come along with us?

[Commander Cleostra]

Silence, Hall. You will return to your quarters. Cleostra.

[Captain Bradford]

But I've best to do as she says, Joan. And I think you should stay with your mother anyhow.

[Joan Gregory]

But Mother is resting. I am of no value to her, and I do so want to see the laboratories with you.

[Commander Cleostra]

Cleostra, if you continue, I will order your arrest and confinement.

[Jerry Hall]

Golly, whiskers. Joan, what's the matter with you?

[Joan Gregory]

There is nothing the matter with me.

Well, there must be. You ought to know these Euclideans well enough to know they mean business and not keep on arguing with the commander.

[Commander Cleostra]

You are being unusually sensible, Hall.

[Captain Bradford]

Jerry's right, Joan. You can't help us any. And I'd feel more comfortable if you stayed with Pat.

[Joan Gregory]

Very well, Captain. I will return to Mother and remain in our quarters.

[Commander Cleostra]

Cleostra is acting in a very peculiar manner.

[Joan Gregory]

Well, maybe she's afraid of something.

[Captain Bradford]

No, I guess she just worried about everything and thought she'd like to go with us.

[Commander Cleostra]

Enough of this useless speculation as to what Cleostra might think. Come. We will enter the laboratories. As we enter, you will preserve silence. Unless directly addressed by one of the scientists.

[Jerry Hall]

We won't say anything.

[Commander Cleostra]

I will open the panel.

[Jerry Hall]

Oh, boy, what a room.

[Commander Cleostra]

Silence. You will follow me. The larger ships ranged along this side of the chamber are submarines. On that side are the rocket ships. One moment while I observe our surroundings. Yes, we are alone in this section. You may speak.

[Jerry Hall]

It's about time. I was going to bust if I

[Joan Gregory]

couldn't say something pretty soon.

[Captain Bradford]

You don't blame me, Jerry? This is quite a sight.

[Commander Cleostra]

There are 25 submarines and 50 rocket ships.

[Jerry Hall]

Oh, boy. 75 of these things and they don't half fill this room.

[Joan Gregory]

Whoever dug these caves sure had plenty of time.

[Commander Cleostra]

These caves are natural, except for the improvements installed by the Euclideans.

[Captain Bradford]

The jury knows that. Commander?

[Commander Cleostra]

Yes?

[Captain Bradford]

Mind if I ask some questions?

[Commander Cleostra]

Proceed.

[Jerry Hall]

And when you get done, I'll ask some.

[Commander Cleostra]

Silence, Hall. Proceed, Captain Bradford.

[Captain Bradford]

Well, we're familiar with the submarines, as

[Commander Cleostra]

you know, as all Euclidia knows only too well.

[Joan Gregory]

Yeah, we sure put one over on all of you when we swiped that other sub.

[Captain Bradford]

Never mind that now, Jerry. We're here to learn all we can about this place.

[Commander Cleostra]

G47 has informed us that you will aid him in certain tests with the rocket ships.

[Captain Bradford]

So he said. But I thought he meant rocket planes, not submarines.

[Commander Cleostra]

These rocket ships are both air and water vessels.

[Jerry Hall]

Huh? These little submarines fly?

[Commander Cleostra]

Precisely.

[Captain Bradford]

But, Commander, there isn't anything about them that looks like a flying machine.

[Commander Cleostra]

They are not airplanes in the ordinary sense of the word. They are rocket planes propelled by a continuous stream of compressed gas bombs until they reach the static zenith at which time they derive their power from the natural electrical impulses in the rarefied atmosphere.

[Jerry Hall]

She's talking to you now, Captain.

[Joan Gregory]

I can't understand any of it.

[Captain Bradford]

I'm not much better off, son. But perhaps the Commander will explain.

[Commander Cleostra]

The explanation will be made by one more proficient in the higher reaches of science. Cheops, the master builder of Euclidea, will explain the construction of the rocket plane.

[Jerry Hall]

Hey, how soon do we see Cheops?

[Cheops]

You may have that honor now.

[Captain Bradford]

How do you do?

[Cheops]

You will not be needed further, Commander.

[Commander Cleostra]

Very well. I will be in my quarters if you need me.

[Jerry Hall]

How soon do we see the rocket ships, Mr. Cheops?

[Cheops]

The term mister is superfluous. I am referred to as Cheops, master builder of Euclidea.

[Jerry Hall]

Yeah, I know.

[Joan Gregory]

Your grandfather built the pyramids or something.

[Captain Bradford]

Never mind that now, Jerry.

[Joan Gregory]

Sorry.

[Captain Bradford]

I should like to inspect the rocket planes as soon as possible.

[Cheops]

We will inspect one at this time.

[Assistant to Cheops]

G47 has ordered that you be given

[Cheops]

a complete explanation as to the mechanical principles involved.

[Captain Bradford]

Yes, the electrical principles also. If you don't mind, I can visualize the possibilities of the compressed gas in the form of rocket power. But the use of atmospheric electrical energy is something I'm not at all clear on.

[Cheops]

That explanation must come from Thales. He will join us later and explain the electrical devices. It is my task to acquaint you

[Assistant to Cheops]

with the physical features of this rocket ship. Before we enter, you will observe the

[Cheops]

fins set into the sides of the ship.

[Jerry Hall]

I was noticing Those things. What good are they?

[Assistant to Cheops]

They are, to use your worldly description

[Cheops]

of them, simply wings.

[Jerry Hall]

Wings?

[Captain Bradford]

Those things are wings folded back into the body of this submarine.

[Cheops]

Precisely.

[Captain Bradford]

And this machine actually flies.

[Cheops]

This rocket ship will consistently maintain a speed of 1,000 miles per hour. And has a cruising range when fully fueled of 10,000 miles.

[Joan Gregory]

10,000 miles?

[Jerry Hall]

Golly whiskers. Enough to fly all over the United States and back here again.

[Captain Bradford]

Just what I was thinking, Jerry.

[Cheops]

And possibly what the designer had in mind.

[Captain Bradford]

Yes, quite possibly. The ship works as a submarine with its wings folded. And an airship with them extended.

[Cheops]

Precisely. Precisely.

[Jerry Hall]

Well, we're over 400ft below the surface of the ocean. I think that thing would have to be made mighty heavy. Or it wouldn't stand the water pressure long enough to get it under the surface.

[Captain Bradford]

Yes, I wondered about that, too, Jerry.

[Cheops]

You are quite observant, Hall. In fact, that matter of pressure is something we have not been able to overcome. And the weight of such a ship,

[Assistant to Cheops]

even a ship made of the finest Euclidean metals. Would prove too great for the best results in the air. Therefore, these ships are carried in floating pressure chambers.

[Cheops]

To within five fathoms of the surface.

[Assistant to Cheops]

And they're released.

[Captain Bradford]

And then, at the end of a flight, they are landed on the water and returned to the lock.

[Cheops]

Precisely.

[Assistant to Cheops]

We will now enter the rocket ship.

[Cheops]

If you don't mind, I will proceed

[Assistant to Cheops]

making the necessary explanations as we go.

[Jerry Hall]

Oh, boy, this is sure some rocket ship. Gee. The whole inside of the thing is full of gadgets.

[Captain Bradford]

Plenty of instruments. All right, Jerry. And everything's made of copper, isn't it?

[Cheops]

The entire structure is tempered copper amalgamated with aluminum.

[Assistant to Cheops]

These various controls, you see, are used in navigation. The action closely paralleling that of a submarine.

[Jerry Hall]

You fly this thing just like you sail it. On the water or under the water?

[Cheops]

Precisely.

[Assistant to Cheops]

And at a speed of a thousand miles an hour. The displacement approaches that of a boat of similar weight in water.

[Captain Bradford]

How soon am I be to the last take a trip in one of these things?

[Assistant to Cheops]

Your first flight is scheduled to begin with the appearance of Thales. We will accompany you.

[Jerry Hall]

Gee, Tex, 10,000 miles we can go. Let's fly over Los Angeles.

[Captain Bradford]

I'm afraid that wouldn't be allowed, Jerry.

[Assistant to Cheops]

You are quite sure it would not be allowed, Captain Bradford? This ship has a cruising range of 10,000 miles. But you will find that it is fueled for a 500 mile run and no more. If you attempt to escape, you would leave us only one course. The escaping ship would be overtaken and destroyed. And it seems hardly likely that you would have time to leave the ship.

[Jerry Hall]

You sure must want us here at

[Cheops]

least we do not want you elsewhere.

[Narrator]

Ugh.
