Muppets and Aeroplanes

In one of the Muppet Christmas Specials (the one where they have to visit Santa to deliver mail because they got so distracted mucking about in the mail room they forgot to actually post their mail), they have to ride on the wing of an aeroplane to get to the North Pole.

Now, discounting the whole amounts of fired that the airline lady should be, would that be physically possible?

I'm going to assume here that the Muppets do breathe. I know, they're puppets, but magic isn't a thing in the Muppet universe, so therefore, Muppets breathe. For the sake of simplicity, I'm going to assume that they require the same sorts of pressure as humans to breathe, since they live on Earth and are considered human-like in other aspects, so why not this?

Due to this, we can assume that they need similar amount of oxygen to breathe and survive. Between 30 and 40 thousand feet is far above the DEATH ZONE, or the altitude at which most humans can survive, simply due to the sheer lack of oxygen that's up there. They wouldn't have chance to acclimatise either, so the hours it would take to get to the North Pole would be filled with altitude sickness which involves, among other things, death.

Also, look at how they're holding on:

Put simply, they're not. Kermit doesn't even have his hands on the plane! There is literally no way they're holding on tight enough to prevent the wind from pushing them off the plane. They've got a very long drop ahead of them, and I don't think they're going to survive that, especially not if they land in the water.

But you see that canonically, they do survive. So, how does that work?

Remember those assumptions that we had to make for it to work realistically? Look at the Muppet's mouths. They don't have any gap at all, implying that they don't need to breathe. This implies that no matter how realistic the Muppets may seem, there is a small amount of magic in there, as they can still talk, backed up by the fact that Santa exists.

So, rather than considering Muppets as human-like, we have to consider them almost like mystical beings. Their powers aren't truly established, other than not being blatantly obvious ones like teleportation, so it could be that, as mystical beings, they have the ability to grip onto any surface, no matter how slippery. So they technically could hold on, and drop at a low enough point that the snow can actually break their fall, especially due to being made of fabric as opposed to flimsy human bodies.

So... I guess it is physically possible, just not for humans. I guess it's a good thing they aren't really human then? And if they're not human then what does that imply about the Muppet world... But that's another theory!

Merry Christmas!
