Further to my previous post. The RAAF had a flying school at Point Cook in Victoria. Several students came from Papua New Guinea. One of the instructors was an arrogant cuss and racist. His particular PNG student was a big lad and very polite. During aerobatic training in a Winjeel side by side single engine trainer, the instructor was particularly caustic at the nationality of the gentle giant he was flying with.
Next thing the PNG student pilot grabbed the stick, rolled the Winjeel inverted and started to pull through. The instructor was unable to over-power the student who announced quite calmly that both were about to die. Obviously his patience with the instructor had been sorely tested.
The instructor pleaded with his student to let go of the controls as the Winjeel was really wiping off height. The student said to the instructor "If you apologize we will not die"
The instructor apologized profusely, the PNG student released the controls and the instructor recovered the aircraft. The student stayed on the pilots course and after graduation returned to PNG and flew Dakotas.
