The phrase, "let's roll" has been used as early as 1908 in the cadence song now called "The Army Goes Rolling Along", which likely extended into tank usage. "The Roads Must Roll", a science fiction story written in 1940 by Robert A. Heinlein, mentions a re-worded version of "The Roll of the Caissons" called "Road Songs of the Transport Cadets".
The three axes of rotation in an aircraft. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.

Dutch roll is an aircraft motion consisting of an out-of-phase combination of "tail-wagging" (yaw) and rocking from side to side (roll). This yaw -roll coupling is one of the basic flight dynamic modes (others include phugoid , short period , and spiral divergence ).
For example, if the right skid contacts an object and becomes the pivot point while the helicopter starts rolling to the right, even with full left cyclic applied the main rotor thrust vector and its moment follows the aircraft as it continues rolling to the right. Quickly applying down collective is the most effective way to stop dynamic ...
An aircraft 'rolling', or 'banking', with its ailerons An aileron and roll trim tab of a light aircraft. An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. [1]
The position of all three axes, with the right-hand rule for describing the angle of its rotations. An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail.
British Airways Flight 2276 was a scheduled international passenger flight from Las Vegas, Nevada, to London, England.On 8 September 2015, the Boeing 777-200ER operating the flight suffered an uncontained engine failure and fire in the left GE90 engine during take-off from Las Vegas-McCarran International Airport, prompting an aborted take-off and the evacuation of all passengers and crew.
