So the result fail, reason when looking at a distance eyes came together therefore under pressure might see 2 runways
I think that is called ocular divergence. I had it when I went to Salisbury, Rhodesia, when I first applied (with three O levels). I passed the aptitude tests, looking at pictures of instrument panels and ticking off what they were indicating. I also passed the interviews done by RRAF officers whom I knew from my Rhodesian army service.
However, I failed on OD so I was offered navigator. My father, ex RAF pilot advised me against this on the basis that if you were going to be killed in an aircraft you may as well be flying it.
I went to an optician in Bulawayo where I lived and I had a course with cards that encouraged my eyes to diverge normally. Whether this worked or not but I went back and the medic passed me on the basis that my eyes must have been tired during the first assessment.
Two weeks later I was in the back of Johnny Johnson's Argosy en route to South Cerney.
I never did pay the opticians bill. I was gone before he sent it.
