In 1941 the rise of air services led to the formal creation of the Air Scout branch that focused on aviation and aeronautical activities. However January 1941 also saw the death of Baden-Powell with Lord Somers becoming Chief Scout. The following year a post-war commission was established to review the movement and which led to the publication of The Road Ahead in September 1945. Post war: 1945-1966 The end of the Second World War had hit the Scout section and the movement as a whole hard with numbers drastically reduced with leaders, Rovers and older Scouts being drafted up for war service. In particular the post-war commission noticed in particular it was difficult to keep older boys in the Scout Troop and The Road Ahead, published in 1945, recommended the creation of a Senior Scout Section with the section officially commencing in October 1946. Scouts over the age of 15 could stay in the Troop, join a Senior Scout Patrol within the Troop, or join a separate Senior Scout Troop which was to consist of at least two Senior Patrols. The end of the war and post-war period also saw a few amendments to the tests and badges first outlined and unchanged since Scouting for Boys in 1908; in January 1944 the tests for Tenderfoot, Second Class and First Calss scouts were revised, October 1946 saw the revised scheme of proficiency badges published and 1958 saw a refresh of the badge tests required. Scouts during this time took part in a number of high-profile events, in addition to Jamborees, that helped to boost the image of the movement. These included the 1948 Summer Olympics, as markers for the marathon, in support roles for the games and one even carried the banner for Belgium in the opening ceremony as well as the 1951 Festival of Britain and assisting with crowd control and programme selling at the 1953 Coronation of Elizabeth II. Additionally a small change to the uniform was made in 1954 to allow Boy Scouts, Senior Scouts and Rover Scouts to opt for a beret as headwear instead of the traditional campaign hat. The high-point of the 1950s was the Golden Jubilee celebrations for the movement in 1957 which included a Jubilee World Scout Jamboree in Sutton Coldfield attracting 35,000 Scouts from 90 countries.
