The previous shot from April 1913 is almost on the eve of the 14/18 War. This scan however is two years earlier in April 1911. It is the somewhat damaged frontispiece of the April issue and marks the change in publication of The Aero from a Weekly to a Monthly magazine. The aircraft of this time were much more fragile than the immediately prewar machine having its engine change where two years of frantic development had lead to bombing trials and the fitting of machine guns, cameras and even radio phones to aircraft.
