In a previous article, Circuit Breaker said:
What I want to know is why the History channel showed an F-15 pilot
wearing standard civilian sunglasses in the airplane during flight, yet
people who require corrective lenses can't fly the plane. At least, this
is what the recruiters have told me. Piloting a fighter jet - of any sort

My understanding is that in the rare years when they have fewer
applicants, they'll take people who need glasses, but usually they have to
weed down the pool, so the first people they cut as the glasses wearers.

But as somebody has already said, if you get in with perfect vision and
later need glasses, you can stay on flying status until they can't be
corrected to 20/20.

Considering that everybody's eye sight gets worse over time, I guess they
figure they'd better start with people with perfect eyesight so there is
less chance it will deteriorate to un-correctable before they've got their
money's worth from you.

Either way, it'll remind the clued that there's only one letter
difference between 'turkey' and 'turnkey'.
