Coronation Aerial Post On 9th September 1911, Gustav Hamel took off from Hendon Aerodrome in his frail Blériot monoplane to inaugurate the first United Kingdom aerial post and landed in Shaw Farm meadow, Long Walk, Windsor. The flight was organised to carry special mail celebrating the coronation of King George V.

Within a few years, Air Mail services became well established, and between 1930 and 1938, special blue pillar boxes like this commemorative one were used for posting Air Letters.

This box is adjacent to the site of Windsor Post Office (1887-1966), where Air Mail was received from the United Kingdom aerial post.

THIS COMMEMORATIVE BOX DOES NOT ACCEPT MAIL
