More typically what happens next in the rolling scissors is that the initial attacker, aware of his vulnerability caused by the overshoot, also rolls his aircraft, and pulls his nose toward the bandit's aircraft. Due to the two components of the initial overshoot (vertical and horizontal), if the pilots keep attempting to turn their noses toward their opponent, then energy management, elements of roll and turn (as in the flat scissors; although in the rolling scissors there are no reverses of turn), as well as climbs and descents will be required to maintain maneuvering that might, if successful, result in a position from which a shot can be made. What evolves therefore in the rolling scissors is a maneuver that is essentially two aircraft barrel-rolling, involving rolling and looping motions, climbing and descending and turning while the aircraft rolls around its longitudinal axis. The barrel roll has a vertical component which the aileron roll lacks. Unfortunately, the two maneuvers are often confused in many contexts, or are used as if they are interchangeable terms. They are not. The "snap roll" is yet another maneuver, commonly seen in aerobatics performances, and is similar to a flat spin (thus involving an aerodynamic stall) and is not typically of any use in ACM) around each other's flight path, which might look like two interwoven cork-screws, or a double helix. The more barrel rolls that are flown in the rolling scissors, the more nearly the rolls become horizontal only, as each pilot attempts to deplete enough forward speed to place his fighter behind the other.
