The 479th FG converted to the P-51 Mustang in mid-September. On his second transition flight, at the point of touchdown during landing, Olds learned a lesson in "false confidence" when the powerful torque of the single-engined fighter forced him to ground loop after the Mustang veered off the runway. Olds shot down an Fw 190 in his new "Scat VI" on October 6 during a savage battle near Berlin in which he was nearly shot down by his own wingman. He completed his first combat tour on November 9, 1944, accruing 270 hours of combat time and six kills.
