Now let me get this straight (and I'm looking at the aresti drawing). You start from level and pitch up 45 degrees, wings still parallel to the ground. Somehow, when you pass the level of the horizontal line defining your barrel axis your plane must be in a 45 degree climbing knife edge. Then you fly a 45 degree corkscrew around the barrel ending at the level of the barrel axis in 45 degree climbing knife and also magically now with wings parallel to to the ground in a 45 degree climb.
