The following planes saw a flash of light. They saw a swiftly descending conflagration tracing a steep arch toward the tree tops. They saw that flaming vanish among the trees. And then they saw a vast upflaring of fire below. Flames licked upward almost to the tree tops....
Bell looked back from two thousand feet. Wing-tip lights were on, below, and disks of illumination played upon the roof of the jungle above the fire. The three planes were hovering over the spot. But a thick dense column of smoke was rising, now. Green things shriveling in the heat, and dried and rotted underbrush. Altogether, the volume of smoke and flame was very convincing evidence that an airplane had burst into flame in mid-air and crashed through the jungle top to burn to ashes beneath.
ut Bell climbed steadily to five thousand feet. He cut out the motor, there, and in the shrieking and whistling of wind as the plane went into a shallow glide, he spoke sharply.
"Paula?"
"I am all right," she assured him unsteadily. "What now?"
"There's a seat pack under you," said Bell. "It's a parachute. You'd better put it on. God only knows where we'll land, but if the motor stops we'll jump together. And I think we'll have to jump before dawn. This plane won't fly indefinitely. There's just one chance in a million that I know of. There'll be a moon before long. When it comes up, look for the glitter of moonlight on water. With the wing-tip lights we may—we may—manage to get down. But I doubt it."
He moved his hand to cut in the motor again. She stopped him.
"If we head south," she said unsteadily, "we may reach the Paraguay. It is perhaps two hundred miles, but it is broad. We should see it. Perhaps even the stars...."
