The big green helicopter was directly in the line of takeoff. The helicopter had landed after blasting the second hole, and now it sat on the tundra about a half mile away. Men in dark green uniforms were outside the hangar preparing for an assault when the wing emerged like a monstrous black bird hatching from its egg. Their surprise quickly turned to terror, and they scattered like leaves before the wind.

The helicopter pilot was leaning against the chopper smoking a cigarette when he saw the monstrous aircraft bearing down in his direction. He jumped back into the helicopter, where he was faced with an immediate decision. He could stay where he was and be rammed. He could fire his rockets or guns at the oncoming wing and hope that his hurried shots would hit the slim fuselage. Or he could head for the sky.

Austin was distracted by the sound of a giant woodpecker rapping on the fuselage. Zavala thought it was one of the engines falling apart and was only partially relieved when Austin said, “They're shooting at us. Are you going to fly this rig or drive it all the way to Nome?”

Because of the unusual position of the instrument panel, Zavala could not see all the gauges. Aiming for the helicopter to keep the plane on a straight line, Zavala shouted at Austin to call out the air speed.

“Forty!” Austin yelled.

Zavala was surprised at how quickly the plane accelerated, despite its huge mass and the partially deflated tires. He had to maintain a firm hand on the controls to keep the nose from lifting.

“Sixty!”

The landing gear hit the water of the shallow lake, but the plane's speed continued to increase.

“Eighty!”

Even as Austin called out, Zavala felt the lightness on the wheel indicating that the plane was near takeoff speed.

“One hundred!”

Zavala counted to ten, then pulled back on the wheel. Both men practically drove their feet through the floorboards as they pressed on imaginary accelerators. The massive plane seemed to leap into the air. Zavala had assumed that they would easily clear the helicopter, but once the plane was up at an angle all he could see was blue sky.

The helicopter pilot had finally chosen a course of action, but it was the wrong one. He mistakenly assumed that the huge bat-shaped aircraft lumbering across the permafrost in his direction would hit the chopper on the ground. He lifted off about the same time Zavala got the wing airborne.

From his level in the copilot's seat, Austin had a clear view of the chopper rising into the path of the flying wing. Unaware of the impending collision, Zavala had been concentrating on the takeoff. From his reading Zavala knew that the wing's rapid acceleration would blow the covers off the slow-moving landing gear. The gear had been designed for slower-moving propeller-driven planes and took too long to retract. Pilots compensated by retracting the gear while the plane was only a few hundred feet off the ground and pulling the nose up at a fairly steep angle.
