Just then, there was a large black shadow overhead and a sudden WHOOSH!

"Whoosh!" Born in the backwoods though he had been, Johnny did not at first recognize that soundhalf grunt, half snort, and full of a terrible meaning.

It gave another "whoosh!"

In seconds, the air inside the dome whooshed out into the vacuum of space.

The pirate went down with a whoosh of air and lay still.
