I’ve heard Kristoferson was a National Guard helicopter pilot, and landed his helicopter on Cash’s lawn to drop-off a copy of the lyrics.
Wiki—” He became a helicopter pilot after receiving flight training at Fort Rucker, Alabama. He also completed Ranger School. During the early 1960s, he was stationed in West Germany as a member of the 8th Infantry Division. It was during this time that he resumed his music career and formed a band. In 1965, when his tour of duty ended, Kristofferson was given an assignment to teach English Literature at West Point. Instead, he decided to leave the Army and pursue songwriting. His family disowned him because of this decision and they never reconciled with him. They saw it as a rejection of everything they stood for, in spite of the fact that Kristofferson has said he is proud of his time in the military, and received the AVA (American Veterans Awards) “Veteran of the Year Award” in 2003.”
