Agreed - with 20/20 hindsight, the Royal Aircraft Factory designers do look like idiots. The BE2 was a pretty good plane when it was first designed and built - before the war. At that time, many other designs also placed the observer in the front cockpit. But those other designers responded to the ever changing requirements of aerial warfare and moved the observer to the rear, plus developed fairly effective gun mounts for the observer to use. But not the Royal Aircraft Factory. They were "comfortable" building the BE2, and saw no good reason to change, despite the BE2 being almost helpless in combat. That bureaucratic resistance to change cost the lives of hundreds of British airmen, and was a contributing factor to Bloody April in the spring of 1917.
