Nobody can simply explain how planes can fly. But that's good news!

Another excellent use of about 5 minutes of my time. Thanks.

Dunno about this presumption, Bernoulli has it pretty much taped in my book.
I was taught as broadly described: a theoretical airmass / fluid separated by the airfoil section, stagnation bubble at the leading edge, laminar flow over upper and lower surfaces and vortices aft of the trailing edge and wingtips..
Surmised that this was demonstrated with visible water vapour under some weather conditions becoming visible over the upper surfaces only due the pressure and resulting temperature drop, and the fact that control surfaces deflected downwards locally increase the camber of the airfoil profile resulting in more lift.
If a full left roll input is made at the point of the stall, which way does the aircraft roll ?
It rolls and then spins to the right as the local angle of attack has increased on the side of the down going control surface, the critical angle has been exceeded and the right wing stalls.
Inverted flight ? Aircraft such as the Pitts have a symmetrical airfoil section and a surplus of thrust .. no problem, try that with a normal wing section and one has to push forward rather hard to keep the nose from falling through the horizon.
Not claiming anything but observation, and until a better explanation appears it seems good enough for me 😇

Yo! Your videos are genuinely good keep it up🎉

To play devil's advocate:

If nobody understands how lift REALLY works, then how did NASA manage to fly Ingenuity on Mars ?

Its the Coanda effect, its kind of because of skin friction

Well, I am an Aerospace Engineering, and I even can't tell the exact reason of creation of lift after studying a lot about it.
One thing I can tell you is that, nature itself is designed like that.
Consider there is a flow, if you put something inside this flow, like an airfoil, the fluid will have to displace around it. Now because of the particular shape of the airfoil, the fluid HAS to flow around it, because the fluid doesn't have any other option to go to. The flow gets split, it doesn't accelerate much on the relatively flatter lower surface, but it has to accelerate to catch up with the flow above the airfoil (because of viscosity).
Resulting in lower pressure, and hence lift.
Bernoulli, Netwon's law, and Venturi effect are correct at thier place, just not the correct explanation of the lift.
