In 1933, aerial cameras had been developed that worked essentially as they do today. Aerial surveys were made, stereo plotters produced maps, and the science of photogrammetry was advancing. However, aircraft development had a long way to go before the SR-71 came along. Over the years, the general complexity of taking photographs from above increased by orders of magnitude. A 1933 British flight in two bi-wing aircraft over Mount Everest on an aerial survey mission is compared to a 1984 Space Shuttle flight dedicated to aerial, or more accurately, space photography. The comparison leads to the conclusion that in exploration, it is important that people involved must be given latitude to exercise self-initiative if we are to be successful in the exploration of the solar system and galaxy.
