True - for a car, the treadmill can prevent it from moving because the rotation of the wheels is a determinant of how fast the car can go. For a plane, however, the wheels have nothing to do with how it accelerates.

If that were so, then you couldn't drive a car on a treadmill.

I just took AP Calc today, and tomorrow I've got Macro. After that I'm done with AP tests forever, things will start to wind down, and within three weeks I'll be done with Step 1 of getting to space.

They would probably fall down and get hurt.

Well, if it helps we know that a treadmill definitely works normally on a spaceship.

No, because while a tailwind is exerting a force on the whole plane, the treadmill is only exerting a force on the wheels, which are always spinning in place relative to the plane.

Yes. No it doesn't. The speed of the treadmill has no bearing on the speed of the airplane, because can assume the wheels have negligible friction, so the only effect of the treadmill's acceleration will be that the wheels spin faster as the plane moves, until it takes off and the treadmill is left wondering what it did wrong.

Thank you @Snark for the wonderful explanation, as always. As I understand it, the treadmill in the traditional problem is not magical, rather it is set to whatever acceleration the plane achieves, but in the opposite direction. So the wheels at any time would be spinning at twice their normal rate, while the plane accelerates to takeoff speed. Additionally, if you'd like you can imagine an airplane taking off from a frictionless flat surface*. Even if the surface begins to move, the airplane will remain at the same velocity, and can take off in any direction, even directly against the motion of the surface. *I'd better not use the word "plane" for this too.

Which basically can't happen, because no matter how fast the treadmill is going the wheels will just spin faster while the plane accelerates in the other direction.

The wheels are not what is propelling the airplane. The wheels will just spin faster on a treadmill while the engines accelerate the plane to regular speed.

HAN SINGULAR, ACTIVATE!

I'm not sure that it would seem any slower, it's just higher resolution.

Don't forget the Blue Danube waltz!

I think there's a search option somewhere in the menu.

That was an incredibly smooth launch, I'm confident they are onto big things with this. And the glide ratio of S1 as it came down makes me feel as if they don't have so much new work to do in getting BFR to land by gliding.

S2 no longer has a line of sight with Bermuda. No worries.

I agree. I don't care for the ultra-processed stuff much. The darker the chocolate, the better. Otherwise it's just like eating a spoonful of table sugar. You know, I'm not a coffee drinker, but I like the smell of it. Maybe I should try coffee ice cream.

I live in the US, and I've been to Brazil and France so far. I like to visit geologically interesting places when I can. I'd like to get to all six continents eventually, plus at least one very productive interplanetary trip.

Scrub.

They don't have enough time anymore to make the launch window with T-15:00.

Perhaps there is place for a god of allergies...

Ah, superintendent Chalmers! Welcome! I hope you're prepared for an unforgettable luncheon!

They disintegrate into Mystery Goo™.

Or you could just leave it kind of weird and abstract. It's kind of interesting. It's your choice.
