Shortly after all this, the British, Americans, Japanese, and other assorted allies invaded Russia, largely, on behalf of the Russian White Army (and to attempt to extricate the Czech legion). That would be the time frame I would expect there to have been conditions that meet the initial post's parameters. Communist pilot vs. Americans in planes capable of landing in open fields. But I haven't found any indication that the US had any (substantial) Air Force present.
There might not have been much of an American Air Force yet, but there were already a fair number of American pilots flying for the French.
