importance of 1st airmail service in india?

Answer 1

Empire Air Mail Scheme
The idea of an Empire Air Mail Scheme was
conceived in 1933. It aimed to carry all first class mail
through the British Empire at a rate of one and a half
pence per half ounce, with a charge of one penny for
postcards. The scheme began on 28 June 1937, when
the flying boat Centurion flew from Southampton to
South Africa. The second stage, to India and Malaya,
began in February 1938 and the third stage to
Australia in July 1938. The Empire Air Mail Service
was intended to last for 15 years, but was halted by
the war and formally ended on 31 March 1947.
Imperial Airways were merged with British Airways
in 1940 to form the British Overseas Airways
Corporation.
