The first aircraft was ordered in September of that year, with delivery expected in 1936; eleven more were ordered in May 1935. An order for a further two aircraft in 1937 brought the total to 14. Production of their Whitley heavy bomber for the Royal Air Force was a priority, and work on the Ensign proceeded slowly. Construction took place not at the main Coventry factory, but at the workshops of Air Service Training Ltd in Hamble. Constant changes were requested by Imperial, slowing production further. As a result, the Ensign's maiden flight did not take place until 24 January 1938. Despite being underpowered, the aircraft was certified, and full airline service began between Croydon and Paris, France in October of that year. Operational history: Three more Ensigns were completed by Christmas, 1938, and were dispatched with the holiday mail to Australia. All three suffered mechanical problems and did not reach their destination; all Ensigns were removed from active airline service and returned to Armstrong for improvements. Reliability was improved, and more powerful Armstrong Siddeley Tiger IXC engines aided performance somewhat. Eleven aircraft were in service at the outbreak of World War II, with a twelfth following soon after, and all were withdrawn in October, 1939 to be camouflaged before flying a new route from Heston and <b>...</b>
