"Maybe he won't notice." "Some chance," groaned Roger, running after Tom and Astro. "That old rocket head wouldn't miss anything!" The three boys raced back to the electric elevator and were silently whisked to the air-lock level. They hurried aboard the Polaris and into the control room. Major Connel was seated in a chair near the chart screen, studying some papers.
Moving with amazing speed for a big man, he donned the space suit in the chamber while the pressure was being equalized. As soon as the air-lock portal opened, he scrambled out on the hull and made his way forward to the bulging firing chambers. Stooping over the empty tube of number six, he examined the ring carefully and began to frown. Moving on to number seven, his frown deepened.
It was going to be a rough ride on the power deck, jammed in behind the firing chambers, but at least he was hidden and more important, free. He listened for the clank of metal shoes on the ladder above him. When he heard them, followed closely by the slam of the air-lock portal, he grinned in satisfaction. Opening one of the plastic bags, he began to eat.
The Skylark moved over to the wreck and Seaton, relinquishing the controls to Crane, donned a vacuum suit, entered the main air-lock and snapped on the motor which sealed off the lock, pumped the air into a pressure-tank, and opened the outside door. He threw a light line to the two figures and pushed himself lightly toward them.
"'Scuse it, please I'll be good," and the careful checking and testing of every vital part of the space-suits went on. Satisfied at last that the armor was spaceworthy, Stevens picked up the coils of drag-line, built of a non-metallic fiber which could retain its flexibility and strength in the bitter cold of outer space, and led the girl into the air-lock. "Heavens, Steve!
He donned a space-suit, filled a looped belt with tools, picked up a portable power-drill, and stepped into the tiny air-lock.
In his hand was a stout little glass flask with a tight-fitting metal top. For a second he held it near the outlet of the pipe; then he snapped the top shut and slipped it back into his pocket as quickly as he had produced it. Slowly we commenced to retrace our steps to the air-lock, our curiosity satisfied by this glimpse of one of the most remarkable developments of modern engineering.
The men, two or three at a time, entered a small round chamber built of steel which was fitted with two air-tight doors at the top and bottom; when they were inside the air-lock, the upper door was closed and clamped tight, just as the gates leading from the lower level of a canal are closed after the boat is in the lock; then very gradually the air in the compartment is compressed by an air-compressor until the pressure in the air-lock is the same as that in the caisson chamber, when the lower door opened and allowed the men to enter the great dim room.
My next shot will be through the nitrogen tank at your air-lock. I wouldn't advise you to be there." The wheel turned once more, as the radio came alive from the other end. "Mr. Blackhawk, do you realize that what you are doing constitutes mutiny in space and will be dealt with accordingly on Earth?
The hoisting of the excavated material is done by a steam engine fixed outside the lock, this engine working a shaft on which there is a drum inside the lock, the shaft passing air-tight through a stuffing box. A separate air-lock, with doors, ladder, etc., complete, is provided to give ingress and egress for the workmen.
