Will circular runways ever take off?
Hmm...interesting idea. first blush thoughts:
headwind changes to a crosswind, changes to a tailwind as you land/take-off?
banked runway means lateral load on the aircraft changes as speed increases, meaning you are slipping or crabbing on the ground?
turning take-off requires higher AOA to produce higher lift in turn? more chance of stall?
Americans don't know haw to drive in a round-about!
the real reason it won't work: drinks slide off the table in 1st class as you taxi to the "threshold".
