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 am from time to time congratulating myself on my general want of success as a lecturer; apparent want of success, but is it not a real triumph? I do my work clean as I go along, and they will not be likely to want me anywhere again. So there is no danger of my repeating myself, and getting to a barrel of sermons, which you must upset, and begin again with.”
—Henry David Thoreau (1817–1862)
“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)
