"Captain."

"L axis, transit, three minima."

"Transition, L axis, thirty kilometers-set!"

"Gay Deceiver."

"I'm not at home but you may record a message."

"Change attitude to climb eighteen point five degrees and report."

"Roger Wilco. Climbing. Ten. Twelve. Fourteen. Sixteen. Eighteen. Mark!"

"Execute!"

We were somewhere else with black sky. "Gay, vertical dive. Execute."

"No trouble, Clyde; enjoy the ride."

"Zebadiah, may I talk with Gay while you look over the terrain? To reprogram that fail-safe."

"Sure, go ahead. Jake, want to scan with binox while I eyeball it? I'll warn before transition."

"Zebadiah, I could give her a scouting program, automatic. Skip the verfliers, skip the climb order; just an 'execute' code word. Place her on course... or I could include course."

"I'll head her manually; the rest is swell-after that fail-safe. What's the code word?"

"'Scout'?"

"Good. Include the 'execute' idea in the code word. Deety, I've decided that I love you for your brain. Not those irrelevant physical attributes."

"Zebadiah, once I've had a bath you may change your mind. I've had a sudden attack of brain fever. You had better program her yourself."

"Mutiny again. I retract and apologize. You smell yummy and should marinate another week. It's not your cortex or your character I love but your carcass-delectable! If it weren't for these seat belts, it would be rape, rape, rape, all the way to the ground. Actually you're sort o' stupid-but what a chassis!"

"That's better. Although I'm not stupid."

"You married me. Res ipsa loquitur! Jake, are you spotting anything?".

"Dry hills, Captain. Might as well move on."

"Zebadiah, will you place her in glide and hold a few minutes?"

"Sure. See something you want to check?"

"No, sir, But when we emerged here, we had seventy-three seconds to impact. We've used twenty-one seconds. I'd like a few moments to insert those preprograms."

I overrode manually and started Gay into a stretched glide while I extended her wings. Then I let Deety and Gay talk to each other. Deety had both changes fully worked out; not once did Gay answer, "Null program."

I was about to warn Deety that Gay was not a sailplane when she reported, "All done, Captain. For the 'S' program I added in an alarm for two klicks Habove-G,"

"Good idea. So now I head west again and give her that 'S' code word-no 'Execute'?"

"Yessir. 'Cept I'd like to try the revised B, U, G, 0, U, T program. It has been less than four minutes since we left. Someone may be in that exact spot."

"Deety, I share your curiosity. But it's like testing a parachute the hard way. Can't we save it until we need it? Then, if there is a glitch, we'll be dead so fast we'll hardly notice it."

Deety said nothing. I waited, then said, "Comment, please."

"No comment, Captain." Deety's answer was toneless. "Hmm- Science Officer....omment, please."

"I have no comment to offer, Captain." (A slight chill?) "Copilot, I require your advice."

"Uh, if the Captain please. Am I privileged to ask for written orders?"

"Well, I'll be dipped in- Gay Bounce! Is there such a thing as a 'space lawyer'? Like 'sea lawyer'? Jake, in general, anyone, save in the face of the enemy, may demand written orders... if he'll risk his career to 'perpetuate evidence for the court-martial he knows will follow. Did it myself once and saved my neck and cost my temporary boss fifty numbers-and I wound up senior to him and he resigned.

"But a second-in-command is in a special position; it is his duty to advise his C.O., even if the C.O. doesn't ask for advice. So I don't see how you can demand written orders on a point already one of your duties. But I won't make an issue of it. I'll direct the Astrogator to log your request, then I can dictate my reply into the log. Then I am going to ground this go-buggy and turn command over to you. Maybe you'll have more luck chairing this debating society than I have had. I wish you luck-you'll need it!"

"But, Captain, I did not ask for written orders."

"Eh?" I thought back. He hadn't, quite. "It sounded as if you were about to."

"I was stalling. I must advise you to follow the prudent course. Unofficially, I prefer to risk the test. But I should not have stalled. I'm sorry that my intransigence caused you to consider relinquishing command."

"I didn't just consider it; I have. Resignation effective the first time we ground. You've bought it, Jake."

"Captain-"

"Yes, Deety?"

"You are correct; the test I suggested is useless, and could be fatal. I should not have asked for it. I'm sorry....ir."

"Me, too! I felt you were being too strict with Deety. But you weren't; you were taking care of us, as you always do, Zebbie. Captain Zebbie. Of course you shouldn't make a risky test we don't need."

I said, "Anyone anything to add?" No one spoke up, so I added, "I'm heading west," and did so. "Gay Deceiver-Bug Out!"

Black sky above us; that "dead sea bottom" far below... . I remarked, "Looks as if a Russian, or one of their flappy craft, is in our parking spot. Deety, your revised program worked perfectly."

"But, Zebadiah-why did you risk it?" She sounded terribly distressed.

"Because all of you wanted to, despite what you said later. Because it's my last chance to make such a decision." I added, "Jake, I'm going to tilt her over. Grab the binox and see if you can identify where we were parked. If that fire is smoking, you can use it for reference."

"But, Captain, I'm not taking command. I won't accept it."

"Pipe down and carry out your orders! It's this damned yack-yack and endless argument that's giving me ulcers. If you won't accept command, then it's up for grabs. But not me! Oh, I'll pilot as the new CO. orders. But I won't command. Deety, how long did Gay pause to make that radar check? At what height?"

"H-above-G was half a klick. Duration I don't know but I can retrieve it. Darling-Captain! You're not really going to quit commanding us?"

"Deety, I don't make threats. Pipe down and retrieve that duration. Jake, what do you see?"

"I've located the fire. Several ornithopters are on the ground. My guess places one of them about where we were parked. Captain, I advise not dropping lower."

"Advice noted. Deety, how about that duration?" I didn't know how to ask for it myself, not having written the program.

Deety retrieved it smoothly: 0.071 seconds-call it a fifteenth of a second. Radar is not instantaneous; Gay had to stop and sweep that spot long enough for a "picture" to form in her gizzards, to tell her whether or not she could park there. A fifteenth of a second is loads of time for the human eye. I hoped that Colonel Frimpsky had been watching when Gay popped up and blinked out.

"Five klicks H-above-G, Captain."

"Thanks, Jake." The board showed dive rate-straight down!-of over seven hundred kilometers per hour, and increasing so fast that the units figure was an unreadable blur, and the tens place next to it was blinking one higher almost by the second.

Most carefully I eased her out of dive, and gently, slowly opened her wings part way for more lift as she slowed, while making a wide clockwise sweep to the east-slowed her dive, that is, not her speed through the air. When I had completed that sweep, and straightened out headed for that column of smoke on course west, I was making over eight hundred kilometers per hour in unpowered glide and still had almost a klick H-above-G I could turn into greater speed.

Not that I needed it- I had satisfied myself by eye of what I had been certain of by theory: an ornithopter is slow.

Jake said worriedly, "May I ask the Captain his plans?"

"I'm going to give Colonel Pistoisky something to remember us by! Gay Deceiver."

"Still aboard, Boss."

I kept my eye on the flappy birds still in the air while I let Gay fly herself. Those silly contraptions could not catch us but there was always a chance that a pilot might dodge the wrong way.

Most of them seemed anxious to be elsewhere: they were lumbering aside

right and left. I looked at the smoke-dead ahead-and saw what I had not noticed before: an ornithopter beyond the smoke.

Jake gasped but said nothing. We were on collision course closing at about 900 kms/hr, most of it ours. Suicide pilot? Idiot? Panicked and frozen?

I let him get within one klick of us, which brought us almost to the smoke and near the deck, about 200 meters H-above-G-and I yelped, "Scout!"

Yes, Deety is a careful programmer; the sky was black, we were ten klicks H-above-G, and so far as I could tell, the same barren hills under us that we had left five minutes earlier-and I was feeling cocky. My sole regret was that I would not hear Colonel Snarfsky try to explain to the Grand Duke the "ghost" craft now used by "British spies."

Did Russian nobility practice "honorable hara-kiri"? Perhaps the loadedpistol symbol? You know that one: The officer in disgrace returns to his quarters and finds that someone has thoughtfully loaded his pistol and placed it on his desk....hereby saving the regiment the scandal of a court.

I didn't want the bliffy dead but busted to buck private. With time to reflect on politeness and international protocol while he cleaned stables.'

I checked our heading, found that we were still pointed west. "Gay Deceiver, Scout!"

Black sky again, the same depressing landscape- "Copilot, is it worthwhile to tilt down for a better look? That either takes juice-not much but some- or it takes time to drop far enough to bite air and do it with elevons. We can't afford to waste either time or juice."

"Captain, I don't think this area is worth scouting."

"Careful of that participle; better say 'exploring."

"Captain, may I say something?"

"Deety, if you are speaking as Astrogator, you not only may but must."

"I could reprogram to put us lower if I knew what altitude was just high enough to let you use elevons. Conserve both time and juice, I mean."

"It seems to be about eight klicks H-above-G, usually. Hard to say since we don't have a sea-level."

"Shall I change angle to arrive at eight klicks H-above-G?"

"How long does it take us to fall two klicks when we arrive?"

She barely hesitated. "Thirty-two and a half seconds."

"Only half a minute? Seems longer."

"Three-two point six seconds, Captain, if this planet has the same surface gravity as Mars in our own universe-three-seven-six centimeters per second squared. I've been using it and haven't run into discrepancies. But I don't see how this planet holds so much atmosphere when Mars-our Mars-has so little."

"This universe may not have the same laws as ours. Ask your father. He's in charge of universes."

"Yes, sir. Shall I revise the program?"

"Deety, never monkey with a system that is working well enough-First Corollary of Murphy's Law. If it is an area as unattractive as this, we'll simply get out. If it has possibilities, half a minute isn't too long to wait, and the

additional height will give us a better idea of the whole area. Gay Deceiver, Scout!"

We all gasped. Thirty kilometers and those barren hills were gone; the ground was green and fairly level-and a river was in sight. Or a canal.

"Oh, boy! Copilot, don't let me waste juice-be firm with me. Deety, count seconds. Everybody eyeball his sector, report anything interesting."

Deety started chanting "... thirteen fourteen fifteen-" and each second felt like ten. I took my hands off the controls to keep from temptation. That was either a canal or a stream that had been straightened, revetted, and maintained for years, maybe eons. Professor Lowell had been right- right theory, wrong universe.

"Deety, how far is the horizon?"

"-seventeen-about two hundred fifty klicks-twenty-"

I placed my hands gently on the controls. "Hon, that's the first time you've ever used the word 'about' with reference to a number."

"-twenty-four-insufficient data!-twenty-six-"

"You can stop counting; I felt a.quiver." I put a soft nose-down pressure on the elevons and decided to leave her wings spread; we might want to stretch this one. "Insufficient data?"

"Zebadiah, it was changing steadily and you had me counting seconds. Horizon distance at ten klicks height above ground should be within one percent of two hundred and seventy kilometers. That assumes that this planet is a perfect sphere and that it is exactly like Mars in our universe-neither is true. It ignores refraction effects, tricky even at home-and unknown to me here. I treated it as geometry, length of tangent for an angle of four degrees thirty-seven minutes."

"Four and half degrees? Where in the world did you get that figure?"

"Oh! Sorry, dear, I skipped about six steps. On Earth one nautical mile is one minute of arc-check?"

"Yes. Subject to minor reservations. With a sextant, or in dead reckoning, or on a chart, a mile is a minute, a minute is a mile. Makes it simple. Otherwise we would be saying a minute is one thousand eight hundred fifty-three meters and the arithmetic would get hairy."

"One-eight-five-three point one-eight-seven-seven-oh-five plus," she corrected me. "Very hairy. Best not convert to MKS until the last step. But, Zebadiah, there is a simpler relation here. One minute of arc equals one kilometer, near enough not to matter. So I treated H-above-G, ten klicks, as a versine, applied the haversine rule and got four degrees thirty-seven minutes or two hundred seventy-seven kilometers to the theoretical horizon. You see?"

"I see everything but how you hide haversine tables in a jump suit. Me, I hide 'em in Gay... and make her do the work." Yes, I could nose her over now-easy does it, boy.

"Well, I didn't, exactly. I calculated it, but I did it the easy way: Naperian logarithms and angles in radians, then converted back to degrees to show the relationship to kilometers on the ground."

"That's 'the easy way'?"

"It is for me, sir!"

"If you're quivering your chin, stop it. I told you it was your luscious body, not your brain. Most idiots-savants are homely and can't do anything but their one trick. But you're an adequate cook, as well."

That got me a stony silence. I kept easing her nose down. "Time for binox, Jake."

"Aye aye, sir. Captain, I am required to advise you. With that last remark to the Astrogator you risked your life."

"Are you implying that Deety is an inadequate cook? Why, Jake!"

Hilda interrupted. "She's a gourmet cook!"

"I know she is, Sharpie... but I don't like to say it where Gay can hear- Gay can't cook. Nor has she Deety's other talent which 'tis death to hide. Jake, that's a settlement below."

"Of sorts. A one-church village."

"Do you see ornithopters? Anything that could give us trouble?"

"Depends. Are you interested in church architecture?"

"Jake, this is no time for a cultural chat."

"I'm required to advise you, sir, This church has towers, something like minarets topped off with onion-shaped structures."

"Russian Orthodox!"

Hilda said that. I said nothing. I eased Gay's nose up to level flight, lined her up with what I thought was downstream, and snapped, "Gay, Scout!"

The canal was still in sight, almost under us and stretching over the horizon. I was almost lined up with it. Gay, Scout!

"Anybody see that settlement that was almost ahead before this last transition? Report."
