Working on the flight deck we had to constantly turn our head from side to side because with the flight deck helmets, the goggles, and the ear protection or head phones it was very difficult to know what going on around you. And everything around you will kill you. Much like driving down a freeway having all your windows in your car blacked except for your front windshield.
Saw one young green shirt step the wrong way and walk right into the prop of an E2 Hawkeye during a night launch.
By habit I still do the side by side with the head these 30 years later.
So . . . you’re guy who, when the light turns green, looks left and right before proceeding? Okay. I promise not to lay on the horn any more.
There is a reason us “seasoned” NCOs tell the new guys to “keep their head on a swivel” and “grow eyes in the back of your head”
