The only flying Brewster Corsair will be at the show this year. Chance Vought designed and initially built the F-4U Corsair. Because of the demand during WWII Chance Vought, like all other manufacturers, subbed out additional production of their planes to other companies. The Brewster Corporation was one of the companies to open up a production line for Chance Vought Corsairs. The Brewster corporation only built 735 planes and then went bankrupt.  The F3A-1 (Corsair Mk. III) was the designation for the Brewster-built F4U-1.
