PROFESSOR PUGSLEY was the first to have popularized the term ‘philosophy’ in connexion with airworthiness. Generally, unless structures are completely safe they are regarded as unsafe. A flying machine, however, can at best be only approximately safe. Hence the need for an a priori definition of safety. Not only is it necessary to make a statistically definable sacrifice of safety to obtain a machine which will fly at all, let alone lift an economical payload, but this sacrifice must be spread in a certain manner to give acceptable returns.
