Wasn't there a maneuver that involved a quick pull- up and rudder turn that the French called a "virillle" (sp).
The exact french word is "vrille" and it means a spin, so nothing to do with it. "Vrille à plat" is a flat spin.
The pull-up and rudder + ailerons 180° turn was called an Immelmann in WW1. ("Renversement" in french)
Later, until today, the Immelmann refers to a half loop followed by a half barrel roll to reverse heading and gain altitude (the opposite of a Split-S which is a half barrel roll followed by a half loop downwards) The half loop itself can be combined with some rotation to come out in any direction.
What was called an Immelmann in WW1 is now called a Hammerhead.
