His "answers" are terrible.

How do we deal with a rejected takeoff - as the plane could be headed in any direction when it needs to climb.

His answer - As there is no end to the runway, a starting aircraft can keep rolling and come to a stop

If you don't understand what a rejected takeoff is (i.e., you don't land, so you can't "keep rolling"), how can we take this seriously?

That video of a plane descending, turning at an angle, trying to keep perfectly parallel to the runway, is enough to say "really bad idea". It looks like stunt flying.
