mmitch, neither your link nor any UK media explained why and how the Brig. General in question attained such an august rank. It certainly wasn't in HM Forces where all such personnel scarcely made it to SO (the highest rank I recall was of a Polish Wing Commander). It transpires that he returned to Czechoslovakia in August 1945, in a Spitfire! Thus his last flight in one that he mentions, in December 1945, could have been there.
This piece speaks of shameful persecution after 1948. One can only imagine what that entailed, and was the very reason that most BoB pilots from Eastern Europe preferred to end their Service careers as JOs in the RAF. This is an amazing and brave man, though presumably he spent most of his career as a VSO within the Warsaw Pact. A pity that it wasn't thought appropriate to pad out the spiel in these sound bite pieces and tell us rather more!
