Many of the former ‘colonies’ world-wide owe their modern development to bush flying and aviation in general.
A Canadian example from… January 1929, W.R. ‘Wop’ May and Vic Horner of Commercial Aviation in Edmonton flew medical supplies, in an Avro Avian, some 500 miles (with stops) to Fort Vermillion, though snowstorms, darkness, and of course no modern navigation aids (supplies then shipped via dog-sled to Little Red River to counter a Dyptheria outbreak)
May to go on to record more than 20 ‘mercy’ flights between 1932 and 1934 in the Alberta/Northwest Territories area, ferrying medical supplies and wounded/sick miners, trappers, adults, children, doctors and police.
