Austin stared at the heaving sapphire surface of the sea. He pushed aside thoughts of the two men locked into a steel ball half a mile below the ship’s hull and focused on the retrieval of the bathysphere as a salvage problem. His nimble mind began to formulate a rescue plan and assemble the equipment he would need to carry it out.

He called the captain back. “I’ve got an idea, but I’ll need your help.”

“Tell me what you want and it’s yours, Kurt.”

“Thanks, Captain. I’ll meet you in the machine shop.”

The Beebe’s machine shop, below the main deck, was a vital component of the ship’s operation. A research vessel is basically a platform that allows scientists to plumb the depths with instruments or underwater vehicles. Powerful ocean forces constantly battered the vessel. The Beebe’s shop kept the ship operational with a crew of only three, including the chief mechanic, and an array of tools to cut, grind, turn, mold, mill, and press.

Austin had until then kept the shop busy tending to the specialized needs posed by the bathysphere’s launch. As project director, he had developed a close professional relationship with the chief machinist, a burly, troll-like man named Hank, who liked to wrap up a project with the words, “Good enough for government work.”

Hank must have heard about the B3 because he greeted Austin with a somber face. “What can I do to help, Kurt?”

Austin unfolded the diagram of the B3 and spread it out on a table. He pointed to the horseshoe-shaped metal swivel that joined the cable to the top of the sphere.

“I need to snag the bathysphere here.” Austin sketched out a hook attached to the end of a cable and showed it to Hank. “Can you put this setup together in less than an hour?”

“Forty-five minutes, tops,” Hank said. “I’ll splice the cable to a spare hook. But, I’ll be honest, I can’t give you something that is likely to last for the half-mile haul back up to the surface.”

“I’m only interested in the first ten or twenty feet,” Austin said. “Once the B3 is clear of the muck, it can trigger its own flotation system.”

“Getting the hook attached to the swivel is going to be tough at this depth,” Gannon said. “The gap between the swivel and the top of the B3 is only a few inches.” He held his thumb and forefinger up. “Like trying to snag something this size from a helicopter half a mile in the air. It would be almost impossible, in my opinion.”

“I disagree,” Austin said. “It would be absolutely impossible. That’s why I’m not going to do it from the surface.”

“How are you . . . ?”A thoughtful look came to the captain’s face. “Bubbles?”

“Why not? She’s been tested to five thousand feet.”

“But . . .”
