To me the book read as though it had been serialised or was for younger readers. Nearly every chapter repeated information that was in the previous chapter! I was surprised the authors did not question the response of Otto Skorzeny when asked about the mission. Turning it down was not an option if Hitler or Himmler had ordered it!
And on a technical note - the Fielster Storch is a single engine plane, not a twin engine as written in the book.
