It may have slipped your mind but airforce = aircraft and eyes are sort of useful when trying to hit tgts on the ground or avoiding them in the air.
As an aside CAP 774: The avoidance of other traffic is ultimately the pilot’s responsibility - good eye health tends to help with that.
Is it beyond your comprehension that airforce = a lot of people who never enter the cockpit? Eyes are sort of useful for everyone doing everything and not just useful when trying to hit tgts on the ground or avoiding them in the air
Fixing aircraft needs eyesight etc etc.
There are approx 2080 pilots in the RAF - about 5% of the total manpower. The other 95% all carry out essential duties that help in putting the weapon platform where it needs to be, when it needs to be there, with the correct load for the task required. The aircrew are there for the last 5% of that task.
Keep yourself in context. Those who fail to do so end up looking like the current batch of MPs when they tell us that we won't understand and we are just jealous.
