Then, at the last possible instant, the Hun's nerve gave—or, rather, it gave just an instant too late. Billy had a momentary vision of the thin wing-edges flashing wide, of the black crosses on the under side, of a long narrow strip of underbody and tail suddenly appearing below the line of the planes; and then, before he could move or think, he felt the Y221 jar violently, heard horrible sounds of splintering, cracking, tearing, had a terrifying vision of a great green mass with splashed ugly yellow spots rearing up over the top plane before his startled eyes, plunging past over his ducking head with splintering wreckage and flapping streamers of fabric whizzing and rushing about his ears. Y221—whirling, jolting, twisting all ways and every way at once apparently—fell away in a series of sickening jerks that threatened to wrench her joint from joint. Billy's thoughts raced down ahead of them to where they would hit the ground 15,000 feet below ... how long would it take ... would they hit nose-first or how ... was there anything he could do?—and before his mind shaped the question he had answered it—No, nothing! Dully he noticed that their engine had stopped, that Charger apparently was busy at the controls; then—with a gleam of wondering hope, dismissed at first, but returning and growing—that the lurching and rolling was steadying, that they were coming back on an even keel, were ... yes, actually, were gliding smoothly down.
Charger twisted and looked down overside, then back at Billy and yelled, "D'ye see him?" Billy looked over, and next instant saw a vanishing shape with one wing folded back, saw another wing that had torn clear floating and "leafing" away on its own. The shape plunged plummet-wise until it was lost in the haze below. Billy turned inboard. "Broken in air," he shouted, and Charger nodded and turned again to his controls. Billy saw that their propeller was gone, only one jagged splinter of a blade remaining.
They made a long glide back and a good landing well behind the lines on a grass field. "What happened?" said Billy the moment they had come to rest. "He flinched, of course," said Charger. "Ran it a bit fine, and our prop caught his tail and tore it up some. I dunno that we're much hurt, except for the prop and that broken strut."
And, amazingly enough, they were not. The leading edge of a top plane was broken and cracked along its length, one strut was snapped, the propeller gone, a few jagged holes from bullets and Hun splinters ripped in their fabric. "God bless the people who built her!" said Charger piously. "Good stuff and good work in that old 'bus, Billy. That's all that brought us through."
Billy mopped his brow. "Hope we don't meet any more of that breed of Hun," he said. "I find I don't like collisions—not one little bit."
"He flinched at the finish, though," said Charger simply. "They all do."
When they got Y221 back to the 'drome and overhauled her they found her wrenched a bit, but in a couple of days she was tautened up into trim and in the air again.
And the very next morning, as if this weren't enough, Charger and Billy had another nerve-testing. They were up about 12,000 and well over Hunland when they ran into a patch of Archies, and Charger turned and led the formation straight towards a bank of white cloud that loomed up, solid looking as a huge bolster, before them. The sun was dead behind them, so Billy at first sat looking over the tail on the watch for any Huns who might try to attack "out of the sun" and its blinding glare. But as it was dead astern over the tail Billy could see clearly above and behind him, so that there was no chance of a Hun diving unseen from a height, and they were moving too fast to be overtaken on the level "out of the sun." Billy turned round and watched the cloud they were driving at. The sun was full on it, and it rose white and glistening like a chalk cliff—no, more like a—like a—— Billy was idly searching his mind for a fitting simile, when his thoughts broke and he yelled fiercely and instinctively in warning to Charger. But Charger had seen too, as Billy knew from his quick movement and sudden alert sit-up. The cloud was anything round a hundred yards from them, and they could just see the slow curling twisting movement of its face. And—what had suddenly startled them—they could see another machine, still buried back in the cloud, and looming large and distorted by the mist, but plainly flying out of it and straight at them.
What followed was over and done in the space of seconds, although it may seem long in the telling, as it certainly was age-long in the suspense of the happening and waiting for the worst of it. Billy perhaps, powerless to act, able only to sit tense and staring, felt the strain the worst, although it must have been bad enough for Charger, knowing that their slender hope of escape hung on his quick thinking and action. This was no clear case of following his simple plan of charging and waiting for the Hun to flinch. The whole success of the plan depended on the Hun seeing and knowing the charge was coming—on his nerve failing to meet it. Charger didn't even know this was a Hun. He might be one of ours. He might have seen them, and at that very second be swerving to miss them. He might be blinded in the cloud and know nothing of them driving full-on into him. All this went through Charger's mind in a flash, and almost in that same flash he had decided on his action and taken it. He thrust the nose of Y221 steeply down. Even in the fraction of time it took for him to decide and his hand to move the control lever he could see the difference in the misty shape before him, could judge by the darkening, hardening and solidifying outline the speed of their approach. And then, exactly as his bows plunged down, he saw and knew that what he feared had happened—the other pilot had seen him, had thought and acted exactly as he had. Charger saw the thin line of the edge-on wings broaden, the shadowy shape of the tail appear above them, just as he had seen it so often when the Hun he charged had flinched and ducked. But then the flinching had meant safety to him driving straight ahead—now it meant disaster, dipping as he was fairly to meet the other.
Again for the fraction of a second he hesitated—should he push on down, or turn up? Which would the other do? And again before the thought was well framed it was decided and acted on. He pulled the stick hard in, zoomed up, and held his breath, waiting. The shape was clearer and harder, must be almost out of the cloud—doubtful even now if Y221 had time and room to rise clear—all right if the other held on down, but——
