Polar Exploration and Survey by Air
Published online by Cambridge University Press: 28 July 2016
Extract
One of the latest branches of scientific research in which aircraft have been employed is that of polar survey and exploration. It is well known how much time can be saved, and how much labour avoided by using aircraft for surveying large areas of difficult country. There is probably no part of the world more difficult of access than the regions surrounding the two Poles, and there is certainly no part of the earth where exploration and survey is harder to carry out.
