A Spitfire of the 303 squardron flown by Sqn.Ldr. Jan Zumbach with the 'Donald Duck' painted on its side which came from Zumbach's nickname.

The 303 squadron played a very significant role in the Battle of Britain joining more than 150 fellow Polish pilots in this crucial encounter. The squadron’s performance was extraordinary. It shot down 126 enemy planes and lost merely eight pilots in the effort, far surpassing the performance of any British squadron and earning itself permanent membership in the ranks of the most illustrious military formations in aviation history.
