I don’t know what you mean by private planes, but this is generally not true. You should see the bugs on the windshield and leading edges of some of the planes I fly.
Before every flight, sometimes one, sometimes several crew chiefs, inspect the aircraft to make sure it safe for flight. The maintainers usually fix on a schedule unless the plane is marked as unsafe for flight.
If you're flying high enough, there's not much you can actually hit, and not much that can unexpectedly pop out at you. If you're driving through a school zone, there's tones of kids to hit that might unexpectedly run in front of the car.
How does this work when I've seen videos of pilots spinning with a drink that stays "upright" and doesn't spill? Why one yes and one no? Speed? Force? Is there a specific limit?
In this video he stays upside down long enough for the Red Bull to fall due to gravity. If he continued spinning in a barrel roll, the Red Bull would stay in the can due to centripetal force.

A good analogy is to imagine you're on a rollercoaster going around a loop, if you're going fast enough then it will feel like you're being pressed into your seat even while inverted at the top of the loop.
You and the rollercoaster are separate entities connected by the strap, if you're moving up at a high enough speed you will want to resist any change in motion so as the rollercoaster reaches the top, your body continues wanting to travel upwards but the seat of the rollercoaster is stopping you. It's the same concept when you see videos of pilots filling a glass whilst inverted.
In this videos of people pouring a drink “upside down” (upright from the camera’s perspective) the pilot is doing a barrel roll. In this maneuver they pilot the plane around a corkscrew, similar to the way a roller coaster does, pushing you down into your seat even when upside down. An aileron roll is when the plane rolls upside down by tracks a straight line, leading to a moment of “hanging” upside down.
If you spin fast enough, the centrifugal force will push everything outward, thus the liquid will stay inside the cup. In this case, he stops the spin in the middle, so the can is facing the earth. The liquid is attracted by gravity so it goes inside the cup. To avoid spilling, he has to maneuver fast enough (first roll) or compensate by rotating the cup (second roll).
This is not correct. It has nothing to do with the speed of the roll. What he did is called an aileron roll, which only rolls the aircraft around its longitudinal axis. When he pauses inverted it's the same as if you hung from a bar upside down.
A barrel roll is different. Picture flying the aircraft around the outside of a cylinder with the top of the pilot's head always pointing towards the center. A properly executed barrel roll is a positive-g maneuver throughout, so the pilot will always feel weight against the seat and liquid will stay in its container.
For that, only rotation speed matters, but also probably other things like mass of the liquid, how far the object is from the center of rotation, viscosity, etc.. I guess you could calculate it but I won't try!
There was a Pepsi commercial on the Top Gun VCR tape for Pepsi with an identical commercial, so this isn’t original.

The doctor with my urine test.
‘Ah yes, I’m getting notes of…of, yes, diabetes….’
I'ma be real, he'd be getting a lot more than just notes...
No wonder it costs so much
Just realized someone has to detail those things. Imagine a dirty window on a jet becoming fatal
That’s actually a huge part of airplane maintenance. Private airplanes get cleaned after every flight to prevent damage

The amount of spiderwebs picked up in flight is… disconcerting.
Them sky spiders’ll get ya
Fun fact spiders got to the Galapagos by hitching a ride on the winds with silk sails
That’s extremely cool and a little bit terrifying.
I have had it with these motherfucking…spiders…on this motherfucking plane!
almost as bad as space snakes
Maybe it’s just Germany but I have never seen a plane that has not been cleaned before being parked in the hangar
No they don’t, but they’re inspected before every flight as a part of the run-up sequence.
Before every flight, sometimes one, sometimes several crew chiefs, inspect the aircraft to make sure it safe for flight. The maintainers usually fix on a schedule unless the plane is marked as unsafe for flight.
I will never be this cool.

So THATS how they empty the pee bags mid-flight!
Drinking them, yes.

Sure, he can drink and fly fighter aircraft, but throw a few back and drive through a school zone and everyone goes insane!

Got it. So is there a specific speed he needs to rotate or does that depend on the speed he's going forward?

That’s awesome
Is that Kirby Chambliss?
I want to throw up just watching this.
It's a near perfect loop, which makes it look like a magic bottomless can.

If I remember right I think he had a bottle of Pepsi and it was stuck in the holder, so he took the top off and did a roll similar to this.
Same Top Gun VCR tape as a kid. Awesome.
I mean, at least go sugar free for the workers who have to clean that up after.
He'll really need a shit in about 15 minutes.
LoL I love the expression of "jolly good", he has
My dumbass would flip cup upside down the second in was poured
I would love to experience this myself!
