M. Maurice Renard is a modern French author with a wide reputation won by his imaginative scientific romances. This story of a thrilling adventure in the air while recalling the exploits of Jules Verne's heroes owes but little to that master who anticipated so many of the scientific appliances which have since become accomplished facts. Supposititious as it may be, it comes legitimately under the heading of "intelligent anticipation". - Summary by London Magazine, September 1910
