Question: What B-29 Superfortress bomber was stationed on Tinian Island?
Context: Tinian International Airport (IATA: TIQ, ICAO: PGWT, FAA LID: TNI) , also known as West Tinian Airport, is a public airport located on Tinian Island in the United States Commonwealth of the Northern Mariana Islands.  This airport is owned by Commonwealth Ports Authority. On 5 August 1950, a nuclear-capable United States Air Force Boeing B-29 Superfortress bomber carrying a Mark 4 nuclear bomb crashed shortly after takeoff from Fairfield-Suisun Air Force Base with 20 men on board.  Twelve men were killed in the crash, including the commander of the 9th Bombardment Wing, Brigadier General Robert F. Travis.  Another seven were killed on the ground when the aircraft exploded.  The base was later renamed after Travis. North Field is a former World War II airfield on Tinian in the Mariana Islands.  Abandoned after the war, today North Field is a tourist attraction.  Along with several adjacent beaches on which Allied forces landed during the Battle of Tinian, the airfield is the major component of the National Historic Landmark District Tinian Landing Beaches, Ushi Point Field, Tinian Island. Birth of the B-29 was a 1945 propaganda film commissioned by the US War Department.  As the name implies, it concerned the production of the B-29 Superfortress bomber and its use in the aerial bombing of Japan in World War II. Aguigan (also known as "Aguihan", based on the Spanish rendition of the native name, "Aguijan", which is still often used as well) is a small bean-shaped coralline island in the Northern Mariana Islands chain in the Pacific Ocean.  It is situated 8 km southwest of Tinian, from which it is separated by the Tinian Channel.  Aguigan and neighboring Tinian Island together form Tinian Municipality, one of the four main political divisions that comprise the Northern Marianas. The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by Boeing, which was flown primarily by the United States during World War II and the Korean War.  It was one of the largest aircraft operational during World War II and featured state of the art technology.  Including design and production, it was the single most expensive weapons project undertaken by the United States in World War II, exceeding the cost of the Manhattan Project by between $1 and 1.7 billion.  Innovations introduced included a pressurized cabin, dual-wheeled, tricycle landing gear, and an analog computer-controlled fire-control system that directed four remote machine gun turrets that could be operated by a single gunner and a fire-control officer.  A manned tail gun installation was semi-remote.  The name "Superfortress" continued the pattern Boeing started with its well-known predecessor, the B-17 Flying Fortress.  Designed for the high-altitude strategic bomber role, the B-29 also excelled in low-altitude nighttime incendiary bombing missions.  One of the B-29's final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and Nagasaki. The Enola Gay ( ) is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line.  On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb.  The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction.  "Enola Gay" participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura.  Clouds and drifting smoke resulted in a secondary target, Nagasaki, being bombed instead. Robert Alvin Lewis (October 18, 1917 – June 18, 1983) was a United States Army Air Forces officer serving in the Pacific Theatre during World War II.  He was the co-pilot of the "Enola Gay", the B-29 Superfortress bomber which dropped the atomic bomb Little Boy on the Japanese city of Hiroshima on 6 August 1945. George B. Zabelka, a Catholic chaplain with the U.S. Army Air Force, was stationed on Tinian Island in the South Pacific in 1945, where he was assigned to 509th Composite Group.  This is the unit of the crews of "Enola Gay" and "Bockscar" (aka Bock’s Car and Bocks Car), that dropped the Atomic Bombs (”Little Boy” and “Fat Man”) on Hiroshima and Nagasaki.  His duties included saying Mass on Sunday and during the week, hearing confessions, talking with the soldiers, and other typical duties of a wartime chaplain. Silverplate was the code reference for the United States Army Air Forces' participation in the Manhattan Project during World War II.  Originally the name for the aircraft modification project which enabled a B-29 Superfortress bomber to drop an atomic weapon, "Silverplate" eventually came to identify the training and operational aspects of the program as well.  The original directive for the project had as its subject line "Silver Plated Project" but continued usage of the term shortened it to "Silverplate".
