The Black Star Passes, John W. Campbell [best motivational books to read .txt] 📗

went on without a pilot, sometimes the New York-St. Louis expresses that would come over the field broadcasting the emergency signal. But always the people were revived with little difficulty, and each time more of the stock of “Piracy, Inc.” was accumulated. The Air Guard seemed helpless. Time and time again the Pirate slipped in undetected. Each time he convinced them that it was an outside job, for the door was always sealed from the outside.

“Dick, how do you suppose he gets away with the things he does right under the eyes of those Air Guardsmen? He must have some system; he does it every time.”

“I have a vague idea,” Arcot answered. “I was going to ask you today, if your father would let us take passage on the next liner carrying any money. I understand the insurance rates have been boosted so high that they don’t dare to send any cash by air any more. They’ve resorted to the slow land routes. Is there any money shipment in sight?”

Morey shook his head. “No, but I have something that’s just as good, if not better, for our purpose. The other day several men came into Dad’s office, to charter a plane to San Francisco, and Dad naturally wondered why they had been referred to the president of the company. It seems the difficulty was that they wanted to hire the ship so they could be robbed! A large group of medical men and cancer victims were going for the ‘treatment.’ Each one of the twenty-five hundred going was to bring along one hundred dollars. That meant a total of a quarter of a million dollars, which is to be left on the table. They hoped the Pirate would gas them and thus cure them! Dad couldn’t officially do this, but told them that if there were too many people for the San Francisco express, two sections would be necessary. I believe they are going on that second section. Only one hundred dollars! A low price for cancer cure!

“Another thing: Dad asked me to tell you that he’d appreciate your help in stopping this ultramodern pirate. If you go down to see him in the morning, you’ll doubtless be able to make the necessary arrangements.”

“I’ll do so gladly. I wonder, though, if you know more about this than I do. Did they try that C-32L mask on an animal?”

“The Pirate was telling the truth. They tried it on a dog and he went to sleep forever. But do you have any idea how that gas does all it does?”

Now Arcot shook his head. “I don’t know what the gas is, but have a lead on how it works. You may know that carbon monoxide will seep through a solid plate of red-hot steel. That has been known for some three hundred years now, and I have to hand it to this Pirate for making use of it. Even in the war of 2075 they didn’t find any practical application for the principle. He has just found some gas that induces sleep in very low concentrations, and at the same time is able to penetrate to an even greater extent than carbon monoxide.”

“I was wondering how he stores that stuff,” Morey commented. “But I suppose he makes it as fast as he uses it, by allowing two or more constituents to react. It might well be simple enough to store them separately, and the airstream blowing past him would carry the gas behind him, permitting him to lay a stream of it in front of the big plane. Is that about it?”

“That was about what I had figured. One of the things I want to do when I go with that Invalid Special tomorrow is to get some samples for analysis.”

“That’s a pretty big order, isn’t it, Dick? How are you going to handle it, or even get it into your apparatus?”

“Easily enough as far as getting the sample goes. I have already had some sample bottles made. I have one of them in the lab⁠—excuse me a moment.” Arcot left the room, to return a few minutes later with a large aluminum bottle, tightly closed. “This bottle has been pumped out to a very good vacuum. I then swept it out with helium gas. Then it was pumped out again. I hope to take this into some gas-filled region, where the gas will be able to leak in, but the air won’t. When it comes to going out again, the gas will have to fight air pressure, and will probably stay in.”

“Hope it works. It would help if we knew what we were bucking.”

The next morning Arcot had a long conference with President Morey. At the end of it, he left the office, ascended to the roof, and climbed into his small helicopter. He rose to the local traffic level, and waiting his chance, broke into the stream of planes bound for the great airfields over in the Jersey district. A few minutes later he landed on the roof of the Transcontinental Airways shops, entered them, and went to the office of the Designing Engineer, John Fuller, an old schoolmate. They had been able to help each other before, for Fuller had not paid as much attention to theoretical physics as he might have, and though he was probably one of the outstanding aeronautical designers, he often consulted Arcot on the few theoretical details that he needed. Probably it was Arcot who derived the greatest benefit from this association, for the ability of the designer had many times brought his theoretical successes to practical commercial production. Now, however, he was consulting Fuller, because the plane he was to take that afternoon for San Francisco was to be slightly changed for him.

He stayed in Fuller’s office for the better part of an hour, then returned to the roof and thence to his own roof, where Morey junior was waiting for him.

“Hello, Dick! I heard from Dad that you were going this afternoon, and
