Skill's weekend teaser

pmsl this is definitely gonna send skill over the edge maybe Bramble can answer ?? Could be here til fx markets open ............

I don't understand how I can ask (multiple times) if my reasoning that the relative ground speed is 0 mph can go so magnificently unanswered.

If my rationale is wrong in that department then my reasoning which follows from that on airspeed also potentially falters and I'll be prepared, subject to a sensible refutation of that rationale, to review my thinking.

For the disbeliever(s):

If it was somehow possible to make the wheels spin backwards while the plane was flying, would it fall out of the sky?

Dolphins.

Small brakes would not stop it from taking off. Dirty great big ones, ones like you described, would. But that is a completely different kettle of fish! A conveyor belt moving opposite to motion is not a 'brake' of any kind, because it does not impart direct force on the plane, it's frictional force is translated into rotational movement of the plane's wheels, ABOUT THEIR AXES - NET MOTION DUE TO THIS IN EITHER DIRECTION ZERO!!!!!

YOu cannot understand this, because you lack the brainpower. end of story.

You nailed the lid on your own coffin in that post above, I owned you, and now you want to talk about brakes, which is like saying 'ooh but what if the engines on the plane were busted, HA then it couldn't take off could it?'

Idiot.

The point is that if the wheels can spin freely while the relative ground speed is 0, they can also spin freely (though slightly faster) while the plane is moving relative to ground.

And we have answered (multiple times) and it's not going into your thick ruddy head:

GROUNDSPEED DOES NOT MAKE A PLANE FLY.
