 Flying at 30,000 feet (9,100 m) put the B-29s above the effective range of Japanese flak. Each Pumpkin bomb mission was conducted by a formation of three aircraft in the hope of convincing the Japanese military that small groups of B-29s did not justify a strong response. This strategy proved successful, and Japanese fighters only occasionally attempted to intercept the 509th Composite Group's aircraft. One B-29 incurred minor battle damage in operations.
