In the deepest recesses of my fading brain, I can vaguely recall travelling at least once travelling between Christchurch (New Zealand) and the small, sunny city of Nelson. These flights were made at probably about two or three thousand feet, safely aboard a venerable DH Dominie (as they were better known in New Zealand, and all-but one flying in NZ at that stage were wartime Brush-built aircraft). These flights were frequently disrupted by the notoriously fickle weather along the South Island's east coast, which resulted in such services being turned back, which resulted in our family (well, Mum and two other brother) having to resort to the railways to ensure we arrived in the right city! These were, after all, scheduled services rather than tourist trips for no other particular purpose.
