Abstract:

Three jet pilots recently flew high G bank maneuvers, while breathing 100 oxygen and wearing anti-G harnesses, as part of an in-flight project for weapons systems development. As a consequence, on more than one occasion, all three pilots experienced shortness of breath, cough, and aching in the chest -- this latter symptom persisted as long as 3 hours following flight. Physical examination was unremarkable. Pulmonary function study revealed a reduction in vital capacity, immediately following flight, of 20-28 as compared to pre- flight levels outside the plane. A partial, reversible collapse of lung tissue aero-atelectasis may be the mechanism for the observed finding, which could conceivably contribute to aircraft accidents, if not modified. Author
