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:
“I do not know if you remember the tale of the girl who saves the ship under mutiny by sitting on the powder barrel with her lighted torch ... and all the time knowing that it is empty? This has seemed to me a charming image of the women of my time. There they were, keeping the world in order ... by sitting on the mystery of life, and knowing themselves that there was no mystery.”
—Isak Dinesen [Karen Blixen] (1885–1962)
“Let us roll all our strength, and all
Our sweetness, up into one ball:
And tear our pleasures with rough strife,
Thorough the iron gates of life.
Thus, though we cannot make our sun
Stand still, yet we will make him run.”
—Andrew Marvell (1621–1678)
