Saburō Sakai
On 13 May 1942, as a member of the Tainan Air Group based at Lae, New Guinea, Handa asked fellow Tainan ace Saburō Sakai to lend him his wingman, Toshiaki Honda, for a reconnaissance mission over Port Moresby. During the mission, the Japanese pilots were ambushed by enemy P-39 fighters and Honda was shot down and killed. Broken in spirit by Honda's death, Handa soon developed tuberculosis and was evacuated to Japan. After fighting the disease for six years, Handa died in 1948, telling his wife on his deathbed, "I have fought bravely all my life, but I could never forgive myself for having lost Sakai's wingman at Lae."
