The Yankee Squadron was a group of mercenary American military aviators who flew for the Spanish Republican Air Force during the Spanish Civil War.

Eddie August Henry Schneider was an American aviator who set three transcontinental airspeed records for pilots under the age of twenty-one in 1930. His plane was a Cessna Model AW with a Warner-Scarab engine, one of only 48 built, that he called "The Kangaroo". He set the east-to-west, then the west-to-east, and the combined round trip record. He was the youngest certificated pilot in the United States, and the youngest certified airplane mechanic. He was a pilot in the Spanish Civil War in the Yankee Squadron. He died in an airplane crash in 1940, while training another pilot, when a Boeing-Stearman Model 75 belonging to the United States Navy Reserve overtook him and clipped his plane's tail at Floyd Bennett Field.
