[Siko54]

Quick question....I've just acquired this fabulous book to help research my Great Uncle and I am curious as to whether Radtke was aircrew who flew for KG54? My German is very limited and I couldn't see any mention of him in the personnel, but he signs off his intro as 'Hauptmann'. I've googled him but the only references I found were to his book and I found no reference at the Luftwaffe career summaries. Cheers!
