Learning to Fly - A Practical Manual for Beginners #245667

Certainly a man who intends to fly should be consti tutionally sound this point is important. When in an aeroplane, one passes very quickly through the air, and such rapid movement — and also the effect of varying altitudes — entail a certain physical strain. A man with a weak heart might find himself affected adversely by flying; While one Whose lungs were not sound might find that his breathing was impeded seriously by a swift passage through the air. More than one fatality, doubtful as to its exact cause, has been attributed to the collapse of a pilot who was not organically sound, or who ascended when in poor health. And here again is an important point. No man, even a normally healthy man, should attempt to pilot a machine in flight when he is feeling unwell. In such cases the strain of flying, and the effect of the swift motion through the air, may cause a temporary col lapse; and in the air, when a man is alone in a machine, any slight attack of faintness may be sufficient to bring about a fatality.
