What does nines in the nose mean?

Answer 1

I'm pretty sure that's military slang for naval aviators...when they have to shoot down like a hijacked plane or something.

Nines in the nose is military slang that intimates close quarters rules of engagement referring a drawn 9mm pistol at point blank range (in an enemies face). I believe 9mm are still carried by pilots on missions as a service weapon in the event of a shoot-down or ejection in hostile territory.
