On the flight deck, Lichtermann slammed the rudder hard over in an attempt to keep the Kondor from spiraling. The thrust from the starboard wing and the drag from the port made the aircraft all but impossible to fly. It kept wanting to nose over to the left and dive.

Kessler was thrown violently against his gun mount, and a loop of ammunition whipped around him like a snake. It cracked against his face, so that his vision went dim and blood jetted from both nostrils. It came at him again and would have slammed the side of his head had he not ducked and pinned the shining brass belt against a bulkhead.

Lichtermann held the plane steady for a few seconds longer but knew it was a losing battle. The Kondor was too unbalanced. If he had any hope of landing it, he had to equalize thrust and drag. He reached out a gloved hand and hit the kill switches for the starboard engines. They wound down quickly. The stationary propeller continued to cause extra drag on the port side, but Lichtermann could compensate, as his aircraft became an oversized glider.

“Kessler, get up here and strap in,” Lichtermann shouted over the intercom. “We’re going to crash.” The plane shot over a mountain guarding a fjord with a small glacier at its head, the ice dazzlingly white against the jagged black rock.

Ernst had his shoulder straps off and was bending to crawl out of the gun position when something far below caught his eye. Deep in the cleft of the fjord was a building constructed partially on the glacier. Or perhaps something so ancient that the glacier had started to bury it. It was difficult to judge scale in his brief glimpse, but it looked large, like some kind of old Viking storehouse.

“Captain,” Kessler cried. “Behind us. In that fjord. There is a building. I think we can land on the ice.” Lichtermann hadn’t seen anything, but Kessler was facing backward and would have had an unobstructed view into the fjord. The terrain ahead of the Kondor was broken ground, with ice-carved hillocks as sharp as daggers. The plane’s undercarriage would collapse the instant they touched down, and the rock would shred the aircraft’s skin as easily as paper.

“Are you sure?” he shouted back.

“Yes, sir. It was on the edge of the glacier. I could see it in the moonlight. There is definitely a building there.”

Without power, Lichtermann had one shot at landing the plane. He was certain that if he tried it out in the open, he and his two remaining crew members would be killed in the crash. Landing on a glacier wouldn’t be a picnic either, but at least there was a chance they would walk away.

He muscled the yoke over, fighting the Kondor’s inertia. Turning the plane caused the wing surfaces to lose lift. The altimeter began to spin backward twice as fast as when he was maintaining level flight. There was nothing Lichtermann could do about it. It was simple physics.

The big aircraft carved through the sky, coming back on a northerly heading. The mountain that had hidden the glacier from Lichtermann’s view loomed ahead. He silently thanked the bright moonlight, because, at the mountain’s base, he could see a field of virgin white, a patch of glacial ice at least a mile long. He saw no indication of the building Kessler had spotted, but it didn’t matter. The ice was what he focused on.

It rose gently from the sea for most of its length before seeming to fall from a cleft in the side of the mountain, a near-vertical wall of ice that was so thick it appeared blue in the uncertain light. A few small icebergs dotted the long fjord.

The Kondor was sinking fast. Lichtermann barely had the altitude to turn the plane one last time to line up with the glacier. They dropped below the mountain’s peak. The glacially shaped rock appeared less than an arms’ span from the wingtip. The ice, which looked smooth from a thousand feet, appeared rougher the closer they fell toward it, like small waves that had been flash-frozen. Lichtermann didn’t extend the landing gear. If one strut was torn off when they hit, the plane would cartwheel and tear itself apart.

“Hang on,” he said. His throat was so dry the words came out in a tight croak.

Ernst had climbed from his position and had strapped himself in the radioman’s seat. Josef was on the flight deck with Lichtermann. The radio’s dials glowed milky white. There were no windows nearby, so the inside of the aircraft was pitch-black. At hearing the pilot’s terse warning, Kessler bent double, wrapping his hands around the back of his neck and clamping his knees with his elbows, as he’d been trained.

Prayers tumbled from his lips.

The Kondor struck the glacier with a glancing blow, rose a dozen feet, and then came down harder. The sound of metal against the ice was like a train racing through a tunnel. Kessler was thrown violently against his safety straps but didn’t dare uncurl himself from his seated fetal position. The plane crashed into something with a jarring bump that sent radio manuals fluttering from their shelves. The wing struck ice, and the aircraft began to spin, shedding parts in chunks.

He didn’t know what was better, being alone in the hull of the plane and not knowing what was happening outside or being in the cockpit and seeing the Kondor come apart.

There was a crash below where Kessler huddled, and a blast of frigid air shot through the fuselage. The Plexiglas protecting the forward gunner’s position had been blown inward. Chunks of ice that were being shaved off the glacier whirled through the plane, and, still, it felt like they were not slowing.

Then came the loudest sound yet, an echoing explosion of torn metal that was followed immediately by the rank smell of high-octane aviation fuel. Kessler knew what had happened. One of the wings had dug into the ice and had been sheared off. Though Lichtermann had dumped most of their gasoline, enough remained in the lines to make the threat of fire a very real one.

The plane continued to toboggan across the glacier, driven by her momentum and the slight downward slope of the ice. But she had finally started to slow. Having her port wing torn off had turned the aircraft perpendicular to her direction of travel. With more of her hull scraping against the ice, friction was overcoming gravity.

Kessler allowed himself a sigh. He knew in just moments the Kondor would come to a complete stop.

Captain Lichtermann had done it. He relaxed the death grip he’d maintained since the shouted warning and was about to straighten in his seat when the starboard wing tore into the ice and was ripped off at the root.

The fuselage rolled over the severed wing and flipped onto its back in a savage motion that nearly tossed Kessler out of his safety belts. His neck whiplashed brutally, the pain radiating all the way to his toes.

The young airman hung dazed from his straps for several long seconds until he realized he could no longer hear the rasping scrape of aluminum over ice. The Kondor had come to a halt. Fighting nausea, he carefully unhooked his belts and lowered himself to the aircraft’s ceiling. He felt something soft give under his feet. In the darkness, he shifted so he was standing on one of the fuselage support members. He felt down and immediately yanked his hand back. He had touched a corpse, and his fingers were covered in a warm, sticky fluid he knew to be blood.

“Captain Lichtermann?” he called. “Josef?”

The reply was a whistle of cold wind through the downed aircraft.

Kessler rummaged through a cabinet below the radio and found a flashlight. Its naked beam revealed the body of Max Ebelhardt, the copilot, who had died in the first instant of the attack. Calling out for Josef and Lichtermann, he trained the light on the inverted cockpit. He spotted the men still strapped to their seats, their arms dangling as limp as rag dolls’.
