navy planes are male because they have the refueling penis. sometimes the f-18s can be power bottoms with the tanker loadout of 4 fuel tanks and the refueling drogue pod.
airforce planes are female because they have the refueling vagina.
the exceptions are the tanker aircraft, which are always male. in the airforce configuration they have a refueling penis and have straight sex with their harem of fighter jet girls. in the navy configuration they're towing their butthole behind them and having gay sex because the navy is gay.
pictured is a female airforce plane which is about to have its refueling pussy penetrated by a tanker.
remember to take notes. there will be a test next thursday.
