Are you kidding?
The B-29 caught fire at altitude. It was a death trap.
The reason for the low level fire bombings of Japan was that they couldn’t be depended on for the high altitude daylight precision bombings the B-17s & B-24s did in Europe.
By the time of the Korean War, the B-29 was improved. But, on the way out.
“The reason for the low level fire bombings of Japan was that they couldn’t be depended on for the high altitude daylight precision bombings the B-17s & B-24s did in Europe.”
The fire bombings were run at 1500 feet at night! The B-29 flew farther, faster and with a larger payload than the B-17. The reason B-17’s weren’t used on Japan was because they were not capable of bombing Japan.
Precision bombing during WWII did not exist. For example:
” It took 108 B-17 bombers, crewed by 1,080 airmen, dropping 648 bombs to guarantee a 96 percent chance of getting just two hits inside a 400 x 500 ft (150 m) German power-generation plant.”
