Problem: Paul Warfield Tibbets Jr. was born in Quincy, Illinois, on 23 February 1915, the son of Paul Warfield Tibbets Sr. and his wife, Enola Gay Tibbets. When he was five years old the family moved to Davenport, Iowa, and then to Iowa's capital, Des Moines, where he was raised, and where his father became a confections wholesaler. When he was eight, his family moved to Hialeah, Florida, to escape from harsh midwestern winters. As a boy he was very interested in flying.

Because he went to a military school, attended some college, and had some flight experience, Tibbets qualified for the Aviation Cadet Training Program. On 25 February 1937, he enlisted in the army at Fort Thomas, Kentucky, and was sent to Randolph Field in San Antonio, Texas, for primary and basic flight instruction. During his training, he showed himself to be an above-average pilot. He was commissioned as a second lieutenant and received his pilot rating in 1938 at Kelly Field in San Antonio. After graduation, Tibbets was assigned to the 16th Observation Squadron, which was based at Lawson Field, Georgia, with a flight supporting the Infantry School at nearby Fort Benning. It was at Fort Benning that Tibbets met Lucy Frances Wingate, then a clerk at a department store in Columbus, Georgia. The two quietly married in a Roman Catholic seminary in Holy Trinity, Alabama on June 19, 1938. Tibbets did not inform his family or his commanding officer, and the couple arranged for the notice to be kept out of the local newspaper. They had two sons. Paul III was born in 1940, in Columbus, Georgia, and graduated from Huntingdon College and Auburn University. He was a colonel in the United States Army Reserves and worked as a hospital pharmacist. He died in West Monroe, Louisiana, in 2016. The younger son, Gene Wingate Tibbets, was born in 1944, and was at the time of his death in 2012 residing in Georgiana in Butler County in southern Alabama. While Tibbets was stationed at Fort Benning, he was promoted to first lieutenant and served as a personal pilot for Brigadier General George S. Patton, Jr., in 1940 and 1941. In June 1941, Tibbets transferred to the 9th Bombardment Squadron of the 3d Bombardment Group at Hunter Field, Savannah, Georgia, as the engineering officer, and flew the A-20 Havoc. While there he was promoted to captain. In December 1941, he received orders to join the 29th Bombardment Group at MacDill Field, Florida, for training on the Boeing B-17 Flying Fortress. On 7 December 1941, Tibbets heard about the Japanese attack on Pearl Harbor while listening to the radio during a routine flight. Due to fears that German U-Boats might enter Tampa Bay and bombard MacDill Field, the 29th Bombardment Group moved to Savannah. Tibbets remained on temporary duty with the 3d Bombardment Group, forming an anti-submarine patrol at Pope Army Airfield, North Carolina, with 21 B-18 Bolo medium bombers. The B-18s were used as an intermediate trainer, which pilots flew after basic flight training in a Cessna UC-78 and before qualifying in the B-17.

Problem: Joseph Frank "Buster" Keaton (October 4, 1895 - February 1, 1966) was an American actor, comedian, film director, producer, screenwriter, and stunt performer. He was best known for his silent films, in which his trademark was physical comedy with a consistently stoic, deadpan expression, earning him the nickname "The Great Stone Face". Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929, [when] he worked without interruption on a series of films that make him, arguably, the greatest actor-director in the history of the movies". His career declined afterward with a dispiriting loss of his artistic independence when he was hired by Metro-Goldwyn-Mayer and he descended into alcoholism, ruining his family life.

Keaton's personal life had stabilized with his 1940 marriage, and now he was taking life a little easier, abandoning Columbia for the less strenuous field of feature films. Throughout the 1940s, Keaton played character roles in both "A" and "B" features. He made his last starring feature El Moderno Barba Azul (1946) in Mexico; the film was a low budget production, and it may not have been seen in the United States until its release on VHS in the 1980s, under the title Boom in the Moon. Critics rediscovered Keaton in 1949 and producers occasionally hired him for bigger "prestige" pictures. He had cameos in such films as In the Good Old Summertime (1949), Sunset Boulevard (1950), and Around the World in 80 Days (1956). In In The Good Old Summertime, Keaton personally directed the stars Judy Garland and Van Johnson in their first scene together where they bump into each other on the street. Keaton invented comedy bits where Johnson keeps trying to apologize to a seething Garland, but winds up messing up her hairdo and tearing her dress. Keaton also had a cameo as Jimmy, appearing near the end of the film It's a Mad, Mad, Mad, Mad World (1963). Jimmy assists Spencer Tracy's character, Captain C. G. Culpepper, by readying Culpepper's ultimately-unused boat for his abortive escape. (The restored version of that film, released in 2013, contains a restored scene where Jimmy and Culpeper talk on the telephone. Lost after the comedy epic's "roadshow" exhibition, the audio of that scene was discovered, and combined with still pictures to recreate the scene.) Keaton was given more screen time in A Funny Thing Happened on the Way to the Forum (1966). The appearance, since it was released after his death, was his posthumous swansong. Keaton also appeared in a comedy routine about two inept stage musicians in Charlie Chaplin's Limelight (1952), recalling the vaudeville of The Playhouse. With the exception of Seeing Stars, a minor publicity film produced in 1922, Limelight was the only time in which the two would ever appear together on film. In 1949, comedian Ed Wynn invited Keaton to appear on his CBS Television comedy-variety show, The Ed Wynn Show, which was televised live on the West Coast. Kinescopes were made for distribution of the programs to other parts of the country since there was no transcontinental coaxial cable until September 1951.
