Fairly sturdy and easy to fly, the Avro 504 was used by the Royal Naval Air Service to conduct bombing raids into German territory at the beginning of the war. The first plane to strafe troops on the ground, it was also the first British plane to be shot down by enemy ground fire. Better aircraft soon replaced the Avro 504 in combat, but it remained the standard British trainer for the duration of the war.
