A few feet above their heads and a few feet aft, the engines were racing at thousands of RPM, turning gears to drive the seven-bladed main rotor. They had no way of knowing that a fracture was developing in the transmission casing, near the fluid test port.

"Juliet 6, your target has just launched a fighter to escort you in. Will rendezvous in eight minutes. Approaching you at eleven o'clock, angels three."

"Nice of them," Marcks said.

Harrier 2-0

Lieutenant Parker was flying the Harrier that would escort the Super Stallion. A sublieutenant sat in the back seat of the Royal Navy aircraft. Its purpose was not actually to escort the chopper to the Invincible; it was to make a last check for any Soviet submarines that might notice the Super Stallion in flight and wonder what it was doing.

"Any activity on the water?" Parker asked.

"Not a glimmer." The sublieutenant was working the FLIR package, which was sweeping left and right over their course track. Neither man knew what was going on, though both had speculated at length, incorrectly, on what it was that was chasing their carrier all over the bloody ocean.

"Try looking for the helicopter," Parker said.

"One moment . . .There. Just south of our track." The sublieutenant pressed a button and the display came up on the pilot's screen. The thermal image was mainly of the engines clustered atop the aircraft inside the fainter, dull-green glow of the hot rotor tips.

"Harrier 2-0, this is Sentry Echo. Your target is at your one o'clock, distance twenty miles, over."

"Roger, we have him on our IR box. Thank you, out," Parker said. "Bloody useful things, those Sentries."

"The Sikorski's running for all she's worth. Look at that engine signature."

The Super Stallion

At this moment the transmission casing fractured. Instantly the gallons of lubricating oil became a greasy cloud behind the rotor hub, and the delicate gears began to tear at one another. An alarm light flashed on the control panels. Marcks and the copilot instantly reached down to cut power to all three engines. There was not enough time. The transmission tried to freeze, but the power of the three engines tore it apart. What happened was the next thing to an explosion. Jagged pieces burst through the safety housing and ripped the forward part of the aircraft. The rotor's momentum twisted the Stallion savagely around, and it dropped rapidly. Two of the men in the back, who had loosened their seatbelts, jerked out of their seats and rolled forward.

"MAYDAY MAYDAY MAYDAY, this is Juliet 6" the copilot called. Commander Marcks' body slumped over the controls, a dark stain at the back of his neck. "We're goin' in, we're goin' in. MAYDAY MAYDAY MAYDAY."
