Circa 1986, as an enlisted Marine, I applied to the "enlisted commissioning program" to become a naval aviator.

I also do not recall any degree requirement post facto. The limitation of "limited duty officer" meant that no promotion was possible past LtCol (O-5).

I failed the eye test for the USMC, however, I was accepted as a "student naval flight officer". Also, I was offered a transfer to the Navy to become a "student naval aviator", which then accepted up to 20/40 vision in any eye, correctable to 20/20.
