“So you’ve seen it fly?” He gave Jack a sharp look.

“Yes.” Jack told of seeing it leave the island.

“You’d like to know a lot about it?” The man smiled.

“Naturally.”

“Some things I can’t tell you. All I can tell you has been printed in magazines all over the world. Strange you haven’t read them.”

“We’ve been at sea for a long time.”

“Yes, of course.” The man appeared to have accepted Jack’s story as true. “And the facts about our jet plane haven’t been out very long.”

“Jet plane? Is that what you call it?” Jack studied the plane with redoubled interest.

“That’s what it is. It gets its power from jets of air mixed with exploding gas. The jets come out from some part of the plane. I’m not permitted to tell exactly what part. You’ve often watered a lawn, I suppose?”

“Yes, quite often.”
