“More important, where's she going next?” Austin's nimble mind had already sprinted several steps ahead. “Let's go for a boat ride.”

Austin angled his body downward and swam behind the hovering sub. He had once made a dive on the NR-1 and knew a camera was mounted forward of the conning tower. He and Trout grabbed onto the stair rungs built into the sail and hung on. Within seconds, a thin glowing line of yellow light appeared above. The moon pool gates were being retracted.

Trout looked up, the illumination from above reflected in his mask lens. “I think I saw this on The X-Files when the aliens abducted a human.”

“It's always nice to meet new friends,” Austin said, his eyes glued to the line as it widened into a long narrow rectangle, then a square of blazing light.

The sub's vertical thrusters whirred, and the NR-1 rose slowly into the ship. Austin and Trout slid off the deck before the sub surfaced inside the pool. They swam toward a dark area between the circles of illumination cast by the lights inside the ship. At the edge of the pool, they cautiously poked their heads from the water. From the safety of the shadows, Austin took measure. The pool was about two hundred feet long and half as wide. Steel mesh catwalks accessed by short flights of open stairs ran along both sides.

Men in coveralls leaned over the railings and watched the NR-1 emerge from the water. Then the loud grinding of gears filled the enormous chamber as the pool doors closed.

Heavy-duty hoists fitted with steel hooks descended from the ceiling. A door opened in the side of the chamber, and several divers dressed in dry suits jumped into the water. They slid wide yokes under the front and back of the sub. The yokes were attached to the hooks, and powerful winches lifted the sub like the chain falls that were used to yank car engines out.

The hydraulic gates slid shut, sealing the chamber from the sea, and with a mighty grumble, invisible pumps began to suck water from the pool. The powerful pumps cleared the pool in minutes. Then the winches lowered the sub.

Crews of men flowed down the stairs onto the slimy floor of the pool. While some men swept the deck clear of seaweed and flopping fish, others attached cables to the NR-1 and braced it with timbers so it wouldn't shift with the ship's movement. The whoosh of ventilators brought fresh air into the space.
