Why couldn't the runway adapt to these conditions? Why not arrange gigantic superfast hydraulic jacks all along the track, to vary the runway's tilt, according to the needs of the current aircraft? Oh and very flexible and strong runway materials to handle the change in circumference. As long as there were no power failures, this would be a piece of cake.

Frankly, the circular design isn't ambitious enough, as initially proposed.

Yeah - make a huge rotating disc of a runway that rotates at a constant speed, so the pilot can stick the landing at whatever radius has an angular velocity equal to groundspeed.

Then slow down the disk enough to allow taxiing toward the center exit drain.
