Failure to conform to either the pointing or falling reactions required are good and sufficient reasons to reject applicants for cadet pilots.
It is probable that to the layman much of the foregoing will be found technical and scientific, but to the investigator into the physical and psychical phenomena induced by flying, it should be of direct interest. In the medical service of the R.A.F., Canada, the value of these tests in their standardized form was first proved by their application to men who were actually unfit to fly, and the case sheets of many such are on file in that department.
Their adoption only followed after the analysis and continual checking of results obtained by tests not only upon those who desired to take to the air, but also those who, having flown, were reported by their instructors to be unfit to continue, and which showed that they were demonstrably correct, and not merely deduced from a priori assumption.
