Having no legs, the blood is thought to have had less room to drain inside of legless pilots, allowing them to pull tighter turns inside their fighters and thereby kick more ass than your average, full-bodied pilot.
And ass they did kick. Throughout his legless career, Bader took out more than 22 German planes in less than two years. Maresyev completed over 86 combat missions, shot down 11 enemy aircraft (three in a single dogfight) and won the Golden Star of the Hero of the Soviet Union. While Hodgkinson had less time in the air without legs, he managed two kills during the war, the second of which saved the life of Percy "Laddie" Lucas's life, who went on to be the hero of the Siege of Malta, one of the most strategically important battles in all of WWII.
Cracked ranks it as the fourth best battle to watch while totally baked.
When taken in its entirety, it's pretty clear that Marvel could be minting money if they'd latched onto Hodgkinson's story: After losing his legs to an accident that is meant to prepare him for the effects of G-force in battle, he wakes up with an uncanny immunity to the effects of G-force, goes on to take out an F-14 with the oddly ironic superpower his origin story gave him, indirectly allowing the Allies to win one of the most important battles of the most important war in modern history.
