Imperial Airways poster, 1928

This Imperial Airways of Britain poster features the Short Brothers flying-boat the S.8 Calcutta which made its first flight on 14 February 1928, having been launched the previous day. On 15 March 1928, this aircraft (registered as G-EBVG) was delivered by Parker and Brackley to the Marine Aircraft Experimental Establishment, Felixstowe, for its airworthiness and sea handling checks; these were successfully completed on 27 July of the same year and the aircraft was flown back to Shorts on the same day. G-EBVG was handed over to Imperial Airways on 9 August 1928.

The S.8 Calcutta was introduced that year and was used by Imperial Airways flying the Mediterranean to Karachi leg of the Britain to India route.

A total of seven aircraft were built. A military version of the Calcutta, originally known as the Calcutta (Service type), was built as the Short Rangoon. In 1934, a Calcutta was purchased by the French Breguet Company from which they developed a military version for the French Navy known as the Breguet S.8/2, it was similar to the Rangoon version. Four aircraft were built under licence by Breguet at Le Havre. Breguet later developed an improved version the Breguet 521 Bizerte.
