It is probable that air travel will become more prevalent after the war for persons of all ages and that such persons who may have suffered recent illness are likely to consult their physician before undertaking air travel. We believe that this report of a case of spontaneous pneumothorax in which the precipitating factor was the change of atmospheric pressure produced by ascent to 8,000 feet in an airplane, may influence the advice given to patients in this respect.
