As his career had progressed, Thurman Munson had become more and more homesick as his schedule did not allow him enough time to spend at home with his wife and children. Since he kept his home in Ohio during the offseason, he decided that air travel was the best solution and began taking flying lessons. Munson bought a Cessna Citation I/SP jet and by 1979 was regularly using it to transport himself to and from various cities and his home. On one of these trips, where his manager Billy Martin was a passenger, Martin noticed the plane's engine malfunctioned in flight and informed Munson, who discovered the entire engine was destroyed and he had to pay to have a new one installed. Martin grew concerned but was unable to convince Munson to stop.
