The two Polish officers you are thinking of were Sqn Ldr "Iggy" Ignatowski
(Pilot) and Sqn Ldr Bruno Szota (Nav). Both had problems understanding each other in their somewhat fractured English. They had similar problems
when they spoke Polish with very different accents. ( Think of two Englishmen speaking Geordie and Cornish!)
I was in a bar near to Wildenrath on, 45 Air Engineer Course Landaway, in August 73, when a friendly local came to join us for a chat. He asked us if we had been to Germany before - Iggy said he had - in 1943. The German asked what he had been doing. The reply " Making Car Parks!" Less friendly German left.
