Have not seen any comment on Mickiewicz being involved in the Great Escape but then they tend to mention the ones that were shot. Try contacting this museum,
Serwis Muzeum
they may be able to tell you if he was one of them.
Mickiewicz was shot down on 29th August 1941 in a major battle (Circus 88 ) with the Luftwaffe. S/Ldr Jerzy Słoński-Ostoja (306 Squadron) was killed and Mickiewicz became a PoW. He was flying Spitfire Mk IIa P7606 PK*O, a very old machine delivered to Northolt after repair to damage received in an RAF unit. This explains the de Havilland propeller as all Mk IIa were fitted with Rotol propellers at the factory. First photograph shows P7606 before it was given its unit codes. The second in a German scrap yard in France
