In PNG Talair used to have a local "guard" the right prop of the Twotter during the turnaround at some of their stations so no one walked into it. Remember taxing past in a Douglas Islander only to see the "guard" lose his ear. He was back on duty the next day (thankfully) looking like a Sikh due to his turban style bandage!
Trislander was perhaps the worst aeroplane I ever flew (circa 550 hours), an absolute pain to keep loaded properly on multi-sectors in the West Indies, the Islander one of the best (2800 hours+). The Trislander was, however, quieter
The new DHC6-400 sounds great, but at what cost?
