Throughout the years of air displays across the country, the CAF and the many volunteers kept FIFI in the air. In 2006, however, following a series of engine problems, including engine failure occurring during an airshow, the B-29/B-24 Squadron made the difficult decision to ground the aircraft until more reliable engines could be fitted.

In 1942 Chrysler started building the Dodge Chicago Plant, which was ready by early 1944. Wright R-3350 Turbo-Compound radial engine. Two exhaust recovery turbines shown outside impeller casing area (top (silver) and lower (red blading)) that are geared to the crankshaft. By 1943 the new Boeing B-29 Superfortress was flying with R-3350s.
The $3 billion cost of design and production (equivalent to $51 billion in 2022), [1] far exceeding the $1.9 billion cost of the Manhattan Project, made the B-29 program the most expensive of the war. The B-29 remained in service in various roles throughout the 1950s, being retired in the early 1960s after 3,970 had been built.
It was the largest American aircraft to see service in World War II. Each B-29 Superfortress used four of the massive Wright R-3350 - Cyclone 18-cylinder 2,200 horsepower (1,600 kW) engines built at the Dodge Chicago Plant. There were nearly 4000 of these aircraft produced when the B-29 was retired from service in the 1960s.
The B-29A was an improved version of the original B-29 production model. This is the definitive wartime variant of the B-29. All 1,119 B-29A's were built at the Boeing plant in Renton, Washington, formerly used by the United States Navy. Enhancements made in the B-29A included a better wing design and defensive modifications.
The Boeing B-29 Superfortress is a United States heavy bomber used by the United States Army Air Forces in the Pacific Theatre during World War II, and by the United States Air Force during the Korean War. Of the 3,970 built, 26 survive in complete form today, 24 of which reside in the United States, and two of which are airworthy.
The Silverplate project was initiated in June 1943 when Norman Ramsey Jr. from the Los Alamos Laboratory's E-7 Group identified the Boeing B-29 Superfortress as the only airplane in the United States inventory capable of carrying either type of the proposed weapons shapes: the tubular shape of the Thin Man, or the oval shape of the Fat Man.
The Boeing XB-39 Superfortress was a United States prototype bomber aircraft, a single example of the B-29 Superfortress converted to fly with alternative powerplants. It was intended to demonstrate that the B-29 could still be put into service even if the first choice of engine, the air-cooled Wright R-3350 radial engine, ran into development or production difficulties.
