While it may seem like an impossible feat, it is actually possible for a commercial airliner to perform a barrel roll. The key lies in the pilot’s ability to control the amount of g-forces placed on the aircraft during the maneuver. The size of the plane does not matter as much as the pilot’s skill and the amount of airspace available to complete the roll. However, some modern aircraft have built-in limitations to prevent pilots from performing such acrobatic maneuvers.
