A barrel roll is an aerial maneuver in which an airplane makes a complete rotation on its longitudinal axis while following a helical path, approximately maintaining its original direction. It is sometimes described as "a combination of a loop and a roll". The G-force is kept positive (but not constant) on the object throughout the maneuver, commonly between 2-3 G, and no less than 0.5 G.

Famous quotes containing the words barrel and/or roll:
“My long two-pointed ladder’s sticking through a tree
Toward heaven still,
And there’s a barrel that I didn’t fill
Beside it, and there may be two or three
Apples I didn’t pick upon some bough.
But I am done with apple-picking now.”
—Robert Frost (1874–1963)
“Lord, what a thoughtless wretch was I,
To mourn, and murmur and repine,
To see the wicked placed on high,
In pride and robes of honor shine.
But oh, their end, their dreadful end,
Thy sanctuary taught me so,
On slipp’ry rocks I see them stand,
And fiery billows roll below.”
—Isaac Watts (1674–1748)
