Another valuable lesson in aerodynamics and drag learned this weekend. You know how a girl with long hair in a convertible car will have her hair swepped forward as if you driving backwards very fast? It is to do with the drag and low pressure caused behing the windscreen and is the reason why lorries are very inefficient. Well I landed BNIO the other day and thought I would remove some weight before I took off again, so I stood behind the aircraft and remembering the adage of not pi**ing into the wind, I pointed downwind from the propwash and let go. Unfortunately the gusty wind and drag effect of my broad shoulders and impressive physic created the same low pressure area in front of me. At least I dried off quickly in the propwash.
