"Lieutenant (jg) Ralph Hanks, an Iowa pig farmer before the war, became an "ace in a day" by shooting down five Zeros in a single skirmish. In a fifteen-minute air engagement, his throttle never left the firewall and his Hellcat surpassed 400 knots in a diving attack. Hanks had to stand on his rudder pedals and use his entire upper-body strength to keep his stick under control. Intense g-forces caused him to black out several times. This first massed encounter of Zeros and Hellcats did not bode well for the future of the now-obsolete Japanese fighter plane."
