every wondered why serving in the military (especially as officers) tends to run in families?
I worked in DofR in the early 90s. There had been a study which showed that the majority of applicants (all ranks) had at least one close relative who had served in the forces. As the forces get smaller then the pool of such families gets smaller.
Indeed after National Service finished about 1960 this pool was vastly reduced year on year.
I'm not convinced that this necessarily holds for pilots as they have a strong personal drive to fly.
