The above photo shows a corner of the erecting shop in an aeroplane factory "somewhere in England."  Here Fairey Battle bombers are constructed by the latest methods.  The fuselages, with Rolls-Royce Merlin supercharged engines installed, are in the process of completion.  They had a range of 1,000 miles and could travel with a full load at over 250 miles per hour.
