Incorrect terminology?

[Kamak86]

It is true, the term "barrel roll" is used incorrectly: THis was taken from Wikipedia. http://en.wikipedia.org/wiki/Barrel_roll


Aviation
In aviation, the maneuver includes a constant variation of attitude in all three axes, and at the midpoint (top) of the roll, the aircraft is flying inverted, with the nose pointing at a moderate angle to the general path of flight. The term "barrel roll" is frequently used, incorrectly, to refer to any roll by an airplane (see aileron roll), or to a helical roll in which the nose remains pointed generally along the flight path. In fact, the barrel roll is a specific and difficult maneuver; a combination of a roll and a loop. One advantage of the barrel roll over the aileron roll is that it is possible to maintain positive "g" force throughout the maneuver. (If the interior is not immaculately clean any loose material will be thrown about under negative g force and also the aircraft fuel flow may be momentarily interrupted.)

Outside of aerobatic competition, the Boeing 367-80 and Concorde prototype were barrel rolled during testing. The Boeing 367-80 was rolled just once by Tex Johnston in an unauthorized demonstration maneuver while the Concorde was rolled multiple times by her test pilots, including Jean Franchi and Brian Walpole.

One of the best and most accurate depictions of a barrel roll in any aviation movie occurred in the 1966 film The Blue Max, when one of the two German pilots flying a pair of Fokker Dr.I triplanes executes one, as seen from directly behind the pair of aircraft in the film.
