CHAPTER I
IN ACTION OVER THE ARGONNE
"Will that starting signal ever come, Tom?"
"Just hold your horses, Jack. The other squadron has gone out, and is already hard at it over the Boche line. Our turn next. Keep cool. And here's hoping we both pull through with our usual good luck."
"Wow! See that big Hun plane, a Fokker, too, take the nose dive, will you? But he's overshot his mark. I warrant you he is trying like mad to get on a level keel again."
