"In the first over-all design .... no pains should be spared to get the best and most compact disposition of external parts, and the best sizes and forms forthem.....If this is done, using with due commonsense every source of reliable data, and doing everything methodically and thoroughly, it is highly probable that the results will be good, and if one goes on working thus in subsequent designs, altering up empirical constants as found necessary or advisable from increasing experience, one will design better machines, and will know why they are improved."[From F S Barnwell and W H Sayers Aeroplane Design and A Simple Explanation on Inherent Stability (London: McBride, Nast & Co. 1917)]
