We’ve been made that way though.
Granted, there have been, are and will be some total abominations of “Being in charge”

I am not learned regarding the physics of aerodynamics, but just a stab in the dark, I have seen jet fighters do a very quick turn and climb, and seen “Con” trails leaving the very end of the wing tips, is this/could this be the result of both surface air meeting at the trailing edge of the wing and working their way along the wing, to give us what we have seen?.

Yes.
The pressure created literally squeezes the moisture from the air causing it to form up into droplets that are visible.

Yes, it’s working the same as a Winglet. Even more important with qa Rotary wing, as the blade behind is going to chop into disturbed air, so the less you can disturb it, the better.
It also gives a tiny bit more aerodynamic surface for a little increase in rotational diameter. That is important because the 100% nono on a rotating blade (In an engine too) is to allow the tip to go supersonic. So, more surface area within a given maximum diameter at performance RPM.
Oh (Edit) and the winglet on a blade stops some of the “whip” noise too.

By the way, your opening text of the Chinese inventing Gunpowder.
They were actually looking for a potion to extend life.
One day, the mix was at a certain ratio, and the mixer put down his Capstan full strength. Such was he.
It was used in a few fireworks, but not many.
It was years and years later that another bright spark decided to but a bright spark into this powder whist it was in a tube…which lead to a Canon.
I think it was then the Ities which copied it and made a really good job of it into a Canon with umph.

It’s a very edited clip isn’t it.
It looks as stable as a plastic duck in a bath. One gust, buckled wing, pilot is a 6 foot diameter red circle with a Hovercraft on his head.

Ah, funny you should say that as they’re actually very different in principle. We’re still studying how dragonflies and other insects actually fly with a view to improving our own flying machines, but the principle that gives a helicopter its lift is exactly the same as the one that allows fixed wing aircraft to fly.

On a conventional wing an air molecules hitting the leading edge have two choices of where they can go, either over or under the wing. The wing is shaped so those going over the upper surface have a longer path to travel before they arrive at the trailing edge than those going underneath it, but they both actually arrive at the trailing edge at the same time. This creates an area of low pressure over the top of the wing that effectively sucks it upwards. The principle of how a helicopter rotor works is exactly the same, it’s just that rather than relying on the forward motion of the aircraft to get enough air flowing over the wings to produce lift, they’re driven in a circular motion so the aircraft itself can be stationary. I think that may be something we actually did invent! da Vinci’s concept was something more like a ship’s propeller or ‘aerial screw’, an interesting idea for the late 1400’s!

it’s also worth noting that the only creatures in nature to truly conquer the air are insects. Even birds don’t come close to flying as perfectly as insects. 🙂

I know what you are saying, but the bolded bit is actually a myth. Bernoulli’s Law is in force, but the top air doesn’t meet up with it’s previously parted bottom buddy from the Leading edge.

The town deserves it.

Wasn’t it Royal before? Hundreds of years ago?

Good show.
