"But you?"

"I'm coming down. From the forward deck, call the hull control rooms. Order everybody forward and to the deck."

"What about the pressure pumps?"

"I can keep them going from here."

I set the circulating system to guide the fresh air forward, but it was futile against the sucking rush of wind toward the stern. As the pumps speeded up I saw, with the little added pressure, the great cross panel of the stern bulkhead straining harder. It would go in a moment.

Drac was clinging to me. "Tell me what to do!"

"I've told you what to do!" I shoved him to the catwalk. "Get out of here. Get Waters forward. Get the men out of the hull."

His anguished eyes stared at me; then he turned and ran forward on the catwalk. I saw him forcibly dragging the bald-headed Waters from the helio cubby. It was the last time I ever saw either of them.

A buzzer was ringing in the turret, and I plunged back for it. The exertion put a band of pain across my chest, a panting constriction from the lowering pressure.

Fanning, assistant engineer, was still at the pressure pumps. His voice came up: "Pumps and renewers working. Will you use the gravity shifters?"
