Bus driver and former-leader of the German-American Bund, Johannes Kroeger, was picked up by the FBI in the Fall of 1942 and charged with spying:
"Kroeger, the FBI charged, absorbed vital information about plane production while he drove hundreds of aircraft workers in his bus to and from their jobs... He was an old hand at spying for the Nazis and then sending the information to Germany by short wave radio and spy drops in South America. His bus job was just another assignment, the FBI charges."
