Charles Lindbergh, America's most famous pilot at the time, went on a tour of Pacific aviation bases during World War II and secretly flew approximately 50 combat missions where he actively engaged Japanese planes and was almost shot down despite the fact that he was civilian with no active military affiliation.
Lindbergh had become a pilot in a roundabout way. He took flying lessons in Lincoln, Nebraska, in 1922 but didn't progress to solo flight. Instead, he joined a barnstorming show that summer and worked as an aerial daredevil, walking on plane wings and parachuting off.
The next April, he bought a surplus Curtiss JN-4 biplane still in the box, put it together, and tried to fly it. He nearly crashed it soon after takeoff and damaged the wing while landing a moment later. An experienced pilot saw his struggle and offered him a few quick lessons. That afternoon, Lindbergh made a safe solo flight.
He progressed quickly and became an Army Air Reserve pilot and a U.S. Mail Service pilot.
Then, in 1927, Lindbergh took the flight that made him famous. He took off from New York City in a specially modified monoplane and flew for 33.5 hours to Le Bourget Field near Paris in the first solo transatlantic flight.
From that day, Lindbergh was known as the "Lone Eagle." He was awarded the Medal of Honor and the first Distinguished Flying Cross and went on a 48-state tour of America (Alaska and Hawaii were not yet states).
Lindbergh was, unsurprisingly, well-liked in the Army Reserve and promoted, reaching the rank of colonel by the 1930s. But he became friendly with the leaders of Nazi Germany, accepting a Service Cross of the German Eagle from Hermann Goering and championing an "America First" policy that would have seen the U.S. sign a neutrality pact with Adolph Hitler.
In the public fallout that followed, President Franklin D. Roosevelt attacked Lindbergh in the press and Lindbergh resigned his commission in the Army Reserve in 1941. He came to regret the decision that December when he was barred from re-entering the service for World War II.
Unable to fly as a military pilot, Lindbergh got himself a job working for Chance Vought Aircraft, touring Pacific bases and suggesting ways that military pilots could get the most out of their machines, especially when it came to conserving fuel for long flights.
It was during this tour of the Pacific that Lindbergh began suggesting to the services that he be allowed to participate in combat.
The Marines took him up on the offer first and Lindbergh went on a combat patrol, escorting bombers to Rabaul, Papa New Guinea, in a Corsair fighter. Lindbergh did everything the Marine normally in his spot would have done, including strafing Japanese ground targets.
He flew another 13 missions with the Marines before heading to an Army air unit that flew P-38 Lightings.
The parent company of Chance Vought was looking to produce a twin-engined fighter and the P-38 was the premiere twin-engine of the day. Lindbergh pitched that flying with the squadron would allow him to suggest fuel-saving measures and he would be able to evaluate the P-38 design.
He joined the 475th Fighter Group on June 27 and flew five missions before the brass got wind of his presence.
Army Gen. George C. Kenney initially protested Lindbergh's presence and was considering expelling him until Lindbergh suggested that he could get the P-38's combat radius from 570 miles to approximately 700 miles while maintaining a 1-hour time on target.
Kenney relented with the stipulation that Lindbergh not fire his guns. Lindbergh promptly ignored the rule but did work on how to best milk every possible mile out of the P-38's tank without risking the engine.
On July 28, 1944, Lindbergh scored his only aerial victory, downing a Japanese fighter in head-to-head flight during a bomber escort mission. The next week, Lindbergh found himself in the crosshairs as a Japanese Zero nearly shot him before one of the American aces in his group killed the Japanese plane with a machine gun burst.
Kenney heard of both Lindbergh's kill and his near miss and ordered him grounded. Lindbergh left the 475th, but its pilots had already learned his lessons and were able to extend their combat radius to 700 miles, allowing them to protect more American bombers.
On his way home, Lindbergh detoured to visit Marine Corsair units and helped them devise the best way of carrying bombs on the Corsair. He began with a single 1,000-pound bomb but worked his way up to a 2,000-pounder under the fuselage and a 1,000-pound bomb under each wing.
On at least some of these trials, Lindbergh dropped the bombs on Japanese forces bypassed by the American island-hopping strategy. So Charles Lindbergh, a civilian, flew dozens of flights as a bomber, a fighter escort, and in a ground attack role in just a few months, April to September 1944.
