Interestingly, "Flight of the Enola Gay" by Paul Tibbets does not mention this, though other narratives did.
The B-29 did have a major problem with engine fires, due to poor cooling of the engines and magnesium parts. An early test flight of it had such a fire, killing the 11 man crew. This problem was never fully resolved, and the B-29s were pushed into combat with this problem. Having an engine fire somewhere over the Pacific must have been utterly terrifying.
The B-29 also did not have hydraulic boost. It's a much bigger and heavier airplane than the B-17, which also did not have boost. The B-17, under emergency conditions, required a great deal of strength on the part of the pilots. My dad flew B-17s. He said that if 3 engines were out and only one outboard engine was running, it took all of a man's strength stepping on the rudder to keep the airplane straight. Even so, he could only keep it up for 10 minutes at a time, switching between pilot and copilot.
WW2 airplanes were designed with a man's strength in mind. The P-51, for example, required a great deal of strength to control it at high speeds and in emergency conditions.
Women pilots were used to ferry P-51s. Many were lost in crashes. My dad, who also flew P-51s, suspected that they ran into conditions where they weren't strong enough to control it.
The Night Witches flew fighter planes that were half the weight of the P-51, making them well suited for female pilots.
The advent of hydraulically boosted flight controls resolved this. Boeing lightened the "feel" forces on jet airliner controls to accommodate women pilots.
