When was the first official airmail flight service commenced? Name the nations.
The first AIR MAIL services by flight (official) was made by Henri Pecquet in a Humber-Sommer biplane at the United Provinces Exhibition Allahabad, India on 18 February 1911. A load of 6,000 letters and cards was flown 5 miles from Allahabad to Naini Junction, and then sent on by rail.
By arrangement with the Post Office the Graham-While Aviation Co. Britain operated an experimental service between Hendon and Windsor (19 miles) from 9 to 26 September 1911. The first consignment of mail was carried in a Bleriot monoplane piloted by Gustav Hamel, one of four pilots who airlifted 25,000 letters and 90,000 postcards during the three weeks of the service.
The first regular commercially operated airmail service was inaugurated in the German Colony of South West Africa with a Roland biplane which made its initial mail-carrying flight between Swakopmund and Windhoek on 18 May 1914. The service came to a premature end when Union troops invaded the country on the outbreak of World War I.
