TESTS to determine whether certain drugs can be used to counteract “deleterious effects” produced on aviators flying at high altitudes have been undertaken by the City College psychology department at New York. The tests were prompted by the discovery of Army and Navy medical corps that the low oxygen content in the air, the freezing temperature, poor ventilation, noise and boredom with which flying pilots are confronted frequently, cause emotional and muscular disturbances “similar to those induced by drunkenness” and result in errots of judgment that lead to accidents. The study will be conducted for about six months, testing fifty subjects, students and teachers. They are placed in a special chamber for three hours at a time, asked to perform simple tests and their reactions carefully studied. The test chamber can be made to produce rapid changes in temperature and varying oxygen content of the air to create conditions similar to those at 12,000 feet above sea level. This height, it is said, is at the threshold of the most troublesome altitudes. The chamber resembles a refrigerator of the type seen in butcher shops. It is 7 feet square and 10 feet high, insulated by three inches of cork and containing triple plate glass windows for observation. The subject enters through a huge, heavy oak door, containing an “air lock” through which samples of the air-within can be passed outside. The work is under the supervision of Dr. Gardner Murphy) chairman of the Psychology Department; and Dr. Joseph Barmack, head of the psychosomatic laboratories at the college. Secrecy shrouds the survey, due to the effect which positive results would have on military flying, which seems to be going higher and higher. Fighting at 40,000 to 50,000 feet may not be uncommon in the near future.
