Twenty-five feet forward of where they were standing, Carpenter slid open his side screen for the fifth time in as many minutes. The now downward drooping moustache had lost much of its splendid panache but the Wing Commander had obviously decided that there were more urgent considerations in life than waterlogged moustaches. He was wearing goggles now, continuously brushing away snow and moisture with a chamois leather, but the view ahead—or lack of view remained obstinately the same, still that greyly driving snow looming out of and vanishing into that greyly impenetrable opacity, still nothingness. He closed the screen.
A call-up buzzer rang. Carpenter made a switch, listened, nodded.
“Three minutes,” he said to Tremayne. “Oh-nine-two.”
Tremayne made the necessary minute course adjustment. He no longer looked through the side-screen, he no longer even looked at the screen ahead of him. His whole being was concentrated upon flying that big bomber, his all-exclusive attention, his total concentration, on three things only: the compass, the altimeter, and Carpenter. A degree too far to the south and the Lancaster would crash into the side of the Weissspitze: a couple of hundred feet too low and the same thing would happen: a missed signal from Carpenter and the mission was over before it had begun. The young, the absurdly young face was expressionless, the body immobile as he piloted the Lancaster with a hair-trigger precision that he had never before achieved. Only his eyes moved, in a regular, rhythmic, unvarying pattern: the compass, the altimeter, Carpenter, the compass, the altimeter, Carpenter: and never longer than a second on each.
Again Carpenter slid open his side-screen and peered out. Again he had the same reward, the opacity, the grey nothingness. With his head still outside he lifted his left hand, palm downwards, and made a forward motion. Instantly Tremayne's hand fell on the throttle levers and eased them forward. The roar of the big engines died away to a more muted thunder.
Carpenter withdrew his head. If he was concerned, no trace of it showed in his face. He resumed his soft whistling, calmly, almost leisurely, scanned the instrument panel, then turned his head to Tremayne. He said conversationally:
“When you were in flying school, ever hear tell of a strange phenomenon known as stalling speed?”
Tremayne started, glanced hurriedly at the instrument panel and quickly gave a fraction more power to the engines. Carpenter smiled, looked at his watch and pressed a buzzer twice.
The bell rang above the head of the sergeant air-gunner standing by the fuselage door. He looked at the tense, expectant faces before him and nodded.
“Two minutes, gentlemen.”
He eased the door a few inches to test whether it was moving freely. With the door only fractionally open the suddenly deepened roar from the engines was startling but nowhere nearly as dismaying as the snow-laden gust of icy wind that whistled into the fuselage. The parachutists exchanged carefully expressionless glances, glances correctly interpreted by the sergeant who closed the door and nodded again.
“I agree, gentlemen. No night for man nor beast.”
Wing Commander Carpenter, his head once again poked through the side-screen, didn't think so either. Five seconds' exposure to that arctic wind and driving snow and your face was full of porcupine quills: fifteen seconds and the totally numbed skin conveyed no sensation at all, it was when you withdrew you head and waited for the exquisite pain of returning circulation that the fun really started: but this time Carpenter was determined not to withdraw his head until he had complete justification for doing so: and the only justification would be the sighting of the Weissspitze. Mechanically, industriously, he rubbed the chamois leather across his goggles, stared unblinkingly into the greyly swirling gloom and hoped that he saw the Weissspitze before the Weissspitze saw him.
Inside, Tremayne's eyes continued on their rhythmic, unvarying pattern of movement: the compass, the altimeter, Carpenter, the compass, the altimeter, Carpenter. But now his gaze was resting fractionally longer on Carpenter each time, waiting for the sudden signal that would galvanise him into throwing the big Lancaster into a violent bank to port, the only avoiding action they could possibly take. Carpenter's left hand was moving, but he wasn't giving any signal, the fingers of his left hand were drumming gently on his knee. This, Tremayne suddenly and incredulously realised, was probably the highest state of excitement that Carpenter was capable of achieving.
Ten seconds passed. Five. And another five. Tremayne was conscious that, even in that ice-cold cabin, the sweat was pouring down his face. The urge to pull the bomber away to the left, to avoid the shattering, annihilating collision that could be only seconds away now, was almost overpowering.
