    Things like this has been tried before. Remember the circular firing squad? How about the circle jerk? Got to love the yanks adopting the roundabout.

    I love roundabouts. Too much common sense to get most used to.

    I feel like there would be a lot of wing strikes with the runway angled like that. Then try to think about "approach lighting" coming out of an ILS at minimums, as you look for your section of the curve to follow down. Landing from "any direction" wouldn't work if you didn't have a straight line of lights to spot. Also in IFR I don't think they'd want to have more than one plane touching down at the same time, which would take away the efficiency aspect of the circular design. Last of all the "crosswind" would still be an issue as you changed direction in the turn. It would just be harder to compensate for.

    By the way in a situtaion where the landing gear won't deploy or the steering/brakes lock up, I'd like to at least be skidding in a straight line... :confused:

    You could add in that the bank angle is optimized for 140 knots. Therefore, an aircraft with a flap/slat issue and a landing speed around 200 knots will experience significant side load which the airframe may not be able to withstand. Also, go-arounds could end up in any direction including opposite to the landing traffic. Snow and ice would really bugger up things. It would look like The Big One at the Daytona 500! (that's a high-speed multi-car crash for y'all that ain't Southern).

    This is not feasible for a lot of reasons (and I'm not a pilot). First shot of bad weather, and you're trying to land on a banked curve on a wet or frozen runway. Go-arounds would be especially problematic. Depending upon where you are landing, most planes will have crosswinds. There is also the issue of possibly having a tailwind when you're trying to land. Landing in low visibility conditions would be a whole lot of fun, too.

    At least with a straight runway, the wind is usually at a fixed angle in relation to the runway. With a curved runway, that would constantly be changing.
