Pundit Beacon
A Pundit Beacon or Landmark Beacon was an airfield navigational and identification beacon, used by the British Royal Air Force (RAF) in the period around World War II. == Pundit Code == Each airfield was allocated a unique two letter Pundit Code, usually based on the name of the site, such as 'BL' for RAF Beaulieu. By the mid-war period the increasing number of airfields led to overlapping names.
