"But happy," Wyatt said suddenly. "You can see that they're happy."

"Sure, they're happy," Coop chortled. "They're nuts. They got funny looks in their eyes. Happiest guys I know are screwy as—"

The sound which cut him off, which grew and blossomed and eventually explained everything, had begun a few seconds ago, too softly to be heard. Now suddenly, from a slight rushing noise, it burst into an enormous, thundering scream.

They leaped up together, horrified, and an overwhelming, gigantic blast threw them to the floor.


he ground rocked, the ship fluttered and settled crazily. In that one long second, the monstrous noise of a world collapsing grew in the air and filled the room, filled the men and everything with one incredible, crushing, grinding shock.

When it was over there was another rushing sound, farther away, and another, and two more tremendous explosions; and though all in all the noise lasted for perhaps five seconds, it was the greatest any of them had ever heard, and the world beneath them continued to flutter, wounded and trembling, for several minutes.

Wyatt was first out of the ship, shaking his head as he ran to get back his hearing. To the west, over a long slight rise of green and yellow trees, a vast black cloud of smoke, several miles long and very high, was rising and boiling. As he stared and tried to steady his feet upon the shaking ground, he was able to gather himself enough to realize what this was.

Meteors.
