cup of joe

Army’s version: this comes from “a cup of (Jolt Of Energy) joe.” Or, it is a drink as common as the “GI Joe.”
Does G.I. stand for Ground Infantry? General Issue? Galvanized Iron? Government Issued!

Navy’s version: this comes from the secretary of the US Navy, Admiral Josephus ‘Joe’ Daniels who banned the serving of alcohol on ships in 1914, serving nothing stronger than coffee (although the phrase is known to predate his service.)

thanks, Joe! this’s joe’s for you

Yawing turning left and right (rotational, change heading side to side):

Rolling tilting side to side (rotational, about horizontal fore and aft center line):

Long days at sea is the best place to engage in disciplined practices of body movement:

These experienced practitioners show us examples of forward pitch and backward pitch.
