[QUOTE="Hawkear, post: 655210, member: 4728"] Reminds me of the need to prize our ability to Dead Reckon. In the old days before modern aids such as gps navigation, in difficult terrain it was basically dead reckoning ie remembering the way you went in to tell you the way out. I have great admiration for people like Sir Francis Chichester* who in a range limited Gypsy Moth airplane navigated from New Zealand to Australia by island hopping (Norfolk and Lord Howe islands) in the Tasman sea purely by dead reckoning. He calculated wind speed and direction, air speed, correlated with bearings and and occasional sextant fixes and calculations while flying the plane in the cockpit of the aircraft and after a journey of a thousand miles over featureless ocean, dropped right on target. Foolhardy, I would even now say yes but shows us what we can do to navigate without resorting to mod cons. Disclaimer. I am not recommending we do this and ditch our modern aids but we can and should be a little more conscious of our surroundings when we venture into the bush. * One of my favourite books “The lonely sea and the sky” [/QUOTE]
