Muenchen doesn't share Harris' fascination with Great Flying Adventures (see above); in fact his clipped, highly condensed roll call of Antarctic explorations dismisses some of the better known feats (like Byrd's attempt to live alone on the polar ice) as ""stunts."" He does, however, appreciate the solid accomplishments that resulted from the ""age of heroism"" and, later, from the abortive scramble to stake territorial claims on the empty continent, and his discussions of the problems of polar navigation, aerial photography, and specifics of plane models and exploration routes, as well as his protective concern for the fragile polar environment are extras not usually found in fictionalized adventure narratives.
