As the A-17 came over the Irtysh River where it flowed down through a deep gorge cut through the foothills of the Altai Mountains, Teleman suddenly glimpsed a small patch of heat on the infrared screen some thirty miles west of the Kazakh border into Sinkiang. A feeling of elation coursed through him. The whole operation might turn out to be easier than he thought. Ending the coded message that Larkin had transmitted from the ship containing his countering orders was the message "Imperative you procure visual data of war situation." He had to come back with actual photographs of the fighting for the mission to be successful. Without photos, the impact of the conflict between Red China and the Soviet Union would be lost on the world. The public would tend to interpret it as another smoke screen or propaganda play. The patch of heat detected by the infrared sensors could very well lead to those photographs. Teleman examined the IR screen carefully. There, in the.center of the blacked-out snowcovered rock and scrub-covered walls of the gorge that led toward the border was a barely discernible shade of gray, only slightly lighter than the surrounding valley. Teleman pulled around in a tight circle, concentrating visual sensors and cameras on the spot. He had earlier cut his speed from Mach 1.2 to sub-sonic when he had dropped below one hundred thousand feet to avoid sonic boom. Now he throttled back even more, running out the variable geometrical wings until they were extended to the fullest to hold his speed at two hundred knots.
The television cameras were displaying' the deep valley and he carefully began cranking up the image until he could make out a two-wheel track twisting through the rock and paralleling a tiny stream. Shortly a military vehicle came into sight around and from under a shoulder-like overhanging rock. It moved slowly into the open and began to pick up speed along the track. A minute passed and a second vehicle appeared, and then a third.
Teleman brought the aircraft around on the opposite heading and slowed " still further until the fan assemblies engaged and wound up to thirty thousand RPM to provide extra airflow over the wing surfaces to support the aircraft. He was now down to 105 knots. A check of the radar detectors showed nothing more than a routine search patrol nearly eighty miles south, probably Chinese. No scrambled Chinese fighters were recorded. He turned his full attention back to the vehicles again.
The trucks were now moving along the roadway at about forty-five miles an hour, pretty fast for military vehicles on an almost nonexistent road. He cranked the images up to their highest degree of magnification and identified them as Kirov five-ton troop lorries. Ahead of the trucks Teleman could see that the narrow gorge opened up and climbed steeply to a flattish plain that butted sharply against a series of rocky foothills. The foothills appeared to be their destination. -Now he could also see artillery pieces on limbers bouncing along behind each truck. As the trucks reached the spot where the valley began to widen, they had to pass through a narrow defile several hundred yards long. There was no place to turn off the road and, because it snaked through the gap, it would be all but impossible to back out with the artillery pieces. The Chinese must have been waiting for just that moment.
