In 1933 he joined the Polish Air Force school for juniors – SPLDM - on a three years course to train as a pilot, motor, and airframe mechanic. In 1934 he undertook an elementary (eliminating) gliding course at Ustjanowa in the Carpathian mount, achieving category 0, two hours of soaring. After graduating in 1936 he was he was ordered to report as a ground crew corporal to 1st Air Regimment (Pulk Lotniczy) in Warsaw. Once there, he started his pilot training.

On 29 August 1939, together with the whole IV/1 DM (Dywizjon Mysliwski - Fighter Squadron), his unit was relocated from Okecie airbase to Poniatow (near Jablonna) airfield. On 1 September 1939 at 6:00, the P-11c's of 113 EM took off against German raiders. In the air combat that took place north of Modlin, Corporal Cwynar claimed 1 enemy plane destroyed. It was probably a He 111, which fell down in flames. On 6 September, during the afternoon air battle, Cwynar downed one Ju 87 near Lowicz. During the next few days, the air activity of 113 EM was very limited, due to heavy losses and very limited fuel supply. After evacuation via Rumania, Cwynar, like many other Polish pilots, arrived in France. In early June 1940, after receiving a short training on French fighters, Cwynar joined the Polish section in Groupe de Chasse III/6. This group was moved to "Italian Front". Thus, he didn't taste the combat over France.Miachal CwynarAfter its fall, Cwynar went to Britain, the "last hope island."

On 16 September, at 18:30, Cwynar flying Spitfire Mk Vb, (AB914, PK-Z) trounced another Bf-109. On 1 June 1942, Cwynar was commissioned. In October 1942, Squadron 315 was reequipped with Spitfires Mk IX. Cwynar was flying one of IXs (EN123, PK-T) during the mission on 3 February 1943 where at 15:25, he downed an enemy fighter. This time it was a Fw 190. Cwynar was rested, flying as an instructor in 58 OUT (Balado Bridge) in May 1943 and in 61 OUT (Rednal) in October 1943. One month later, he rejoined 315 Squadron.

On 10 July 1944, the squadron was relocated to Brenzett airfield. Cwynar got his first V-1 (shared with another pilot) on July 19, while piloting a Mustang III PK-Z. The next day, he downed another 'half' of V-1 (Mustang III PK-U), and on July 22, he scored 2 'halves' (on PK-N). Finally, on July 24 Cwynar got his 'full' V-1 kill (on PK-Z).
