My father who was an Instructor on Oxfords at RAF South Cerney during WW11 until Mid 1942 had a young Polish Pilot by name of F/Sgt Tadeusz Waclaw Niezrecki who wrote a nice letter when he left S Cerney thanking him for looking after him so well.
This Polish Pilot survived the war and continued in the RAF ending up a Flt Lt . He was involved in a crash in 27/28 April 1942 as co pilot of a Wellington from 301 Squadron. This report was signed by the CO one S/Ldr Krzystyniak. Also in 16 Jan 1942 departing RAF Hemswell with P/O Liska as Captain they crash landed due to lack of Oxygen near Scunthorpe.
Waclaw NIEZRECKI was a Master Pilot in 1952 No 782373 and listed with AFC in London Gazette. I gave his original letter to my father to the RAF Ingham Heritage Centre He also received the DFM . He died 10th June1982. He also received one of the highest Polish Medals VM???
