Jack was a little late, and I went over the _Star’s_ file on the foo fighters. Most of the facts were covered in a story dated July 6, 1947, which had been inspired by the outbreak of the saucer scare. I copied it for later use: During the latter part of World War Two, fighter pilots in England were convinced that Hitler had a new secret weapon. Yanks dubbed these devices “foo fighters” or “Kraut fireballs.” One of the Air Force Intelligence men now assigned to check on the saucer scare was an officer who investigated statements of military airmen that circular foo fighters were seen over Europe and also on the bombing route to Japan. It was reported that Intelligence officers have never obtained satisfactory explanation of reports of flying silver balls and disks over Nazi-occupied Europe in the winter of 1944-45. Later, crews of B-29’S on bombing runs to Japan reported seeing somewhat similar objects. In Europe, some foo fighters danced just off the Allied fighters’ wingtips and played tag with them in power dives. Others appeared in precise formations and on one occasion a whole bomber crew saw about 15 following at a distance, their strange glow flashing on and off. One foo fighter chased Lieutenant Meiers of Chicago some 20 miles down the Rhine Valley, at 300 m.p.h., an A.P. war correspondent reported. Intelligence officers believed at that time that the balls might be radar-controlled objects sent up to foul ignition systems or baffle Allied radar networks. There is no explanation of their appearance here, unless the objects could have been imported for secret tests in this country. I read the last paragraph twice. This looked like a strong lead to the answer, in spite of the Air Force denials. There was another, less pleasant possibility. The Russians could have seized the device and developed it secretly, using Nazi scientists to help them. Perhaps the Nazis had been close to an atomic engine, even if they did fail to produce the bomb. Jack Daly came in while I was reading the story again. “I got the dope on Steele,” he said. “He does pieces for a small syndicate, and I found out he was in the Air Force. I think he was a captain. People who know him say he’s O.K.—a straight shooter.” “That still wouldn’t keep him from giving me a fake tip, if somebody told him it was the right thing to do.” “Maybe not,” said Jack, “but why would they want to plant this foo-fighter idea?” I showed him the clipping. He read it over and shook his head. “That’s a lot different from disks three hundred feet in diameter.” “If we got the principle—or Russia did-building big ones might not be too hard.” “I still can’t swallow it,” said Jack. “These things have been seen all over the world. How could they control them that far away—and be sure they wouldn’t crash, where somebody could get a look and dope out the secret?”
