SCIENTIFIC AMERICAN, New York, Sept. 14, 1912 A nice display issue as the front cover is in color and shows a pilot in an early airplane in a bombing stance (see), plus there is a nice related article inside: "Grenadiers of the Air" "Exploits in Bomb-dropping from Flying Machines" which includes 6 photos. Also inside: "The Flying Boat & Its Possibilities" with 4 photos. The complete issue, minor wear, nice condition.
