Starting the BR with the aircraft track at 90 degrees to the
barrel produces a loop (no roll portion to the BR).
Starting it parallel to the barrel (and reducing the
diameter of the barrel to zero) makes it into an aileron
roll (no loop portion to the BR). Everything in between is
possible, and at some point on either side as you get closer
to the loop or aileron roll, you've got to stop calling it a
BR.


You might not have his thousands of hours, but you certainly
understand a lot more about barrel rolls than does Big John.
:-) :-) Of course, what can you expect from a person who flys
"birds" instead of "airplanes". :-)

May be some definitions...:-)

Barrel Roll....................45 degrees off axis
Aileron roll...................00 degrees off axis
Loop...........................90 degrees off axis
Sloppy barrel roll......22.5-67.5 degrees off axis
Sloppy aileron roll.......01-22.5 degrees off axis
Sloppy loop...............67.5-89 degrees off axis

I think I could do those last three!
