Lulu Belle was the name of his plane. Helen, Frances, and Josephine, were names of his wives.

Gregory "Pappy" Boyington was an American Marine Corps combat fighter pilot during World War II. Boyington received the nickname "Gramps" because he was a decade older than most of the men serving under him. "Gramps" was changed to "Pappy" in a variation on "The Whiffenpoof Song" written by Paul "Moon" Mullen, one of his pilots, and was picked up by war correspondents.

Boyington was initially a P-40 Warhawk fighter pilot with the "Flying Tigers" in the Republic of China Air Force in Burma at the end of 1941 and part of 1942, during the military conflict between China and Japan, and the beginning of World War II.

In September 1942, he rejoined the Marine Corps. In early 1943, he deployed to the South Pacific and began flying combat missions as a Marine F4U Corsair fighter pilot. In September 1943, he took command of the fighter squadron known as the "Black Sheep". In January 1944, Boyington was shot down into the Pacific Ocean after downing one of the enemy planes. He was captured by a Japanese submarine crew and was held as a prisoner of war for more than a year and a half.

He received both the Medal of Honor, the Navy Cross, a Purple Heart Medal and two Presidential Unit Citations for his role in the war.

The television series Baa Baa Black Sheep (starring Robert Conrad) was loosely based on Boyington and his men in the "Black Sheep" squadron.
