A half-hour later he was kicking his Spitfire into line. He was into the air swiftly and laid his course across the serene green countryside to pick up the shore of the North Sea at the nearest point.

At that height it was difficult to realize he was in the sky above a war-torn nation. There were no evidences of destruction below, and the blue sky was clear of enemy planes. The steady throbbing roar of the Spitfire's motor was a pleasantly lulling sound, and he settled back comfortably with his mind at ease, checking over the structural details of the Hendee Hawks in his mind for use in putting the dismantled ships together as fast as possible when he landed at the naval base where they awaited him.

It was pleasant to be out of danger for this brief period. It gave him a chance to examine his thoughts, do a little readjusting of his personal concepts to the grim realities of war. He found he had been under such terrific tension every instant since reporting to the Red Flight that this was the first chance he had found to look back over what had happened and realize how supremely lucky he had been thus far to escape death.

Flying at 4,000 feet, he appeared to be merely creeping across the green blanket of England beneath him. Ahead, he could faintly see a silver line of mist marking the shore of the sea. Though the Spitfire was tunneling through the blue at 350 miles an hour, he suddenly found he was impatient for even more speed. Behind him men were even now fighting and dying. He wanted to get back into it, start doing his part again.

An alien sound obtruded suddenly into the throbbing of his Spitfire. He heard it almost without consciousness of what it portended, then was abruptly aware that a stream of bullets was ripping through his fuselage.

A Heinkel had slid up behind him from nowhere and its smoking guns were streaming hot, leaden death at him. For a moment he was too amazed to properly meet this unexpected danger. He had a curious feeling that it was after him. That it wasn't merely a stray enemy plane making chance contact. It was an absurd thought, but it gripped him strongly and he couldn't shake it off.

Another burst of lead hosed from the Heinkel. Stan rolled the Spitfire to the left, then pulled it up tight and hard. The Heinkel shot under him, went into a loop, then faked a turnover. Stan smiled grimly.

"That won't fool me, son," he muttered. He leveled off fast and eased over into a three hundred yard safety zone. Setting the Spit on her ear, he faced the Heinkel, testing his Brownings as he slid into place.

The Jerry was a crack flier. The Heinkel came in with a roaring thrust, her Madsen slugs drilling away at the Spitfire. Stan heard the stingers zipping through his fuselage. A blue flame began playing up and down over a hole in his fuel tank.

"Well," Stan muttered sourly. "I'll have to put a stop to this, or else——"
