The 'Flugzeug' issue that contained this photo features a number of articles on the Allied experimentation and testing of German aircraft. One article has the memoirs of Royal Navy Captain Eric Brown who flew 55 different German planes, including the Me 163B. The photo shows him seated in the Deutsches Museum Me 163 in 1965.
