Weir shrugged. “Eighteen watts concentrated in a tiny beam that releases a mere two kilowatts of energy doesn’t sound like much, but I promise you it’s ample.”

“How close do you want us to the projectile?”

“The beam divergence makes it necessary to be as near as possible. Less than fifty feet.”

Pitt pressed his mike button. “Al?”

“Come in.”

“Close to within forty feet of the projectile.”

“At that range we’ll be buffeted by turbulence from the copter’s rotor.”

“Can’t be helped.”

Weir flicked the laser’s main switch.

“Do you read me, Abe?” Pitt asked. ,. “I’m listening.”

“The idea is for Giordino to maneuver close enough so we can sever the shroud lines attached to the projectile with a laser beam.” “So that’s the angle,” Sandecker said.

“That’s the angle, Admiral.” Pitt’s voice was soft, almost casual. “We’re moving into position now. Steady on course. Keep whatever fingers you have free crossed and let’s do it.”

Giordino eased the controls with the precision of a watchmaker and slipped the Catlin beside and slightly below the Minerva. He began to feel the chopping wind currents on the control surfaces and his hands tightened about the yoke. Back in the cargo section the violent shaking rattled everything that wasn’t tied down. Pitt alternated his gaze between the projectile and Weir.

The head physicist from Stransky Instruments bent over the laser head. He showed no signs of fear or anxiety. If anything, he seemed to be enjoying himself.

“I don’t see any beam,” said Pitt. “Is it working?” “Sorry to shatter your conceptions,” answered Weir, “but the argon laser beam is invisible.” “How can you zero it in?”

“With this thirty-dollar telescopic rifle sight.” He patted the round tube, which had been hastily screwed to the laser. “It won’t win me the Nobel Prize, but it should suffice.”

Pitt lay on his stomach and crawled until his head was past the threshold of the open hatch. The blasting cold tore at his head bandage, causing one end of the gauze to flap like a flag in a hurricane. The projectile was hanging below the helicopter, trailing at a slight angle toward the tail rotor. Staring at it, Pitt found it difficult to believe a universe of agony and death could be crammed into so small a package. “Closer,” Weir shouted. “I need another ten feet.” “Move in ten feet,” Pitt said over the microphone. “Any closer and we can use a pair of scissors,” Giordino muttered. If he was tense with anxiety, he didn’t show it. His face displayed the expression of one who was half dozing. Only the burning eyes gave any hint of the concentration required for precision flying. The sweat felt like it was exploding inside his cast and the nerve endings in his leg screamed at the irritation.
