What are some words associated with the war that is going on in the book?

From the text:

Ralph danced out into the hot air of the beach and then returned as a fighter-plane, with wings swept back, and machine-gunned Piggy.

"The plane was shot down in flames. Nobody knows where we are. We may be here a long time."

A sliver of moon rose over the horizon, hardly large enough to make a path of light even when it sat right down on the water; but there were other lights in the sky, that moved fast, winked, or went out, though not even a faint popping came down from the battle fought at ten miles' height. But a sign came down from the world of grownups, though at the time there was no child awake to read it. There was a sudden bright explosion and corkscrew trail across the sky; then darkness again and stars. There was a speck above the island, a figure dropping swiftly beneath a parachute, a figure that hung with dangling limbs.
