At the beginning of 1910, he enrolled at the Farman flying school at Mourmelon, and gained Aero-Club de France license no. 81 on 12 April.[6]
Dickson took part in the Lanark flying meet in August 1910, where he won the £400 prize for the greatest aggregate distance flown.[7]
In September 1910, Dickson flew one of the two Bristol Boxkites that took part in the British army manoeuvres on Salisbury plain: his aircraft was captured by the opposing team when he landed to report the result of his reconnaissance by telephone.[8]
On 1 October 1910, while in Milan, Dickson was involved in the first mid-air collision between two aeroplanes. An Antoinette monoplane, piloted by René Thomas of France, rammed Dickson's Farman biplane. Both pilots were injured in the crash.[9] Although Dickson survived, he never fully recovered from his injuries, which contributed to his early death on 28 September 1913.[10] His body was buried in the Highland village of Achanalt in Ross and Cromarty.
