In WWII, what type of airplane did Marine ace Pappy Boyington fly?

In World War II, Marine ace Pappy Boyington flew the Vought F4U Corsair.

Gregory “Pappy” Boyington was a United States Marine Corps fighter pilot who became famous as the commander of VMF-214, nicknamed the Black Sheep Squadron. After returning to the Marines in 1942, he deployed to the South Pacific and began flying the powerful F4U Corsair in combat.

The Corsair was a single-seat fighter recognized by its distinctive inverted-gull wings, large propeller, and rugged design. It was built for speed, heavy armament, and operation from difficult Pacific airfields. Although initially associated with carrier operations, Corsairs became especially effective in Marine land-based fighter units.

Boyington was credited with 28 aerial victories during his career, including victories earned earlier while flying a Curtiss P-40 with the American Volunteer Group, better known as the Flying Tigers. His best-known combat record came in the Corsair, and VMF-214's exploits inspired the later television series Baa Baa Black Sheep. That is why the aircraft answer is more specifically F4U Corsair rather than simply “fighter plane.”
