Operation Hailstone
As TF 58 followed the U.S. strategy of leapfrogging toward Japan, Feightner participated in strikes at the Yap coral atoll of Woleai helping to isolate the Japanese garrison there. At the end of April, the task force returned to Truk in the Caroline Islands. Once a major Japanese stronghold, Truk had been badly damaged during Operation Hailstone earlier that year, but the Japanese had since reinforced the island with aircraft from Rabaul. On April 29, 1944, Feightner shot down a Zeke over Truk, raising his total to six aircraft destroyed.
