I would just like to push back on this narrative of H being “thick as pigshit”.
No, I’m not going to suggest that he’s someone with an over abundance of intelligence but the idea he’s entirely devoid of it lacks credibility.
I appreciate his academic achievements (especially in light of the prestigious education he received) were lacklustre to say the least.
However, you don’t get to fly military helicopters without passing the many required and rigorous tests and assessments regardless of who your father is.
The risks to himself (and arguably more importantly) crew, unit, mission and security of a bloody valuable aircraft etc would not result in him being allowed to shimmy past these requirements as a result of birthright outweighing both safety and security objectives.
In this context I think H is actually misrepresented.
When he chose to apply his mind to something he cared about he succeed.
Is the more likely narrative that he’s stupid or that (at Eton) he saw no gain in competing against peers who were in all likelihood more academically talented than him and had no pressure in the sense that academic attainment would be beneficial to his life trajectory?
I think the case that H is “thick” lacks merit and obscures the likely reality that his primary personal flaw is that of arrogance/egotism.
