The service ran for just under a month, transporting 35 bags of mail in 16 flights; four pilots operated the aircraft including Gustav Hamel, who flew the first service in his Blériot, covering the 21 miles between Hendon and Windsor in just 18 minutes. The service was eventually terminated due to constant and severe delays caused by bad weather conditions. Similar services were intermittently run in other countries before the war, including in Germany, France and Japan, where airmail provision was briefly established in 1912, only to meet with similar practical difficulties.
