An airplane can change direction in three ways because it is free in the air. An automobile can change direction to the right or left, and this corresponds to an airplane yawing left or right. The automobile cannot decide to go down or up like an airplane can because it is on solid ground. This down or up change of direction is called pitch. A car also has wheels only on the bottom, and cannot travel on its roof or on one side. An airplane, however, can fly upside down, or on its side just as well as right side up and changing the position of the plane in this way is called roll. A roll is a technique in an airplane where the plane turns upside down then keeps going until it is rightside up again. Roll on an airplane is controlled by the ailerons (the little flaps on the wings).

If you mean principal palne, it is th e plane of a member where its tension stress is maximum and shear stress zero ( principal stress). It is the highest stress and is often used to compute failure against tensile allowable. Failure will generally occur in the direction of that plane.
Ro Ro is a "Roll On, Roll Off Vessel"
It depends on the size of the roll,
Usually not, but it depends on the context, I mean what kind of stack are you talking about. For example in FORTH language word PICK and ROLL could be used.
Well when you say boeing i'm guessing you mean the plane and yes the boeing defiantly relies on natural resources for example the plane is made out of metal which is a natural resource also the fuel it runs on is fossil fuel which is also a natural resource.
