In this second book in the Captain Mama series, Marco and his sisters, whose mother is a U.S. Air Force aviator, visit the KC-135 aerial refueling tanker on a field trip with his second grade class. The children and their teachers meet the aircrew and the crew chief, tour the airplane to understand its unique parts and learn what each crew member does as they work together onboard this gas station in the sky. Includes a STEM activity for children to learn basic aircraft terms and structure plus glossaries in Spanish and English of aviation terms in the text.
