circular runways.

If you're like me, you assume that a runway is a pretty standard object and that there is not much room for improvement or creativity, outside of some minor material improvements. 

But aviation expert Henk Hesselink disagrees. He's come up with a circular runway. Yes, one big circle runway to replace multiple straight runways in a, he argues, much more efficient set-up. Smaller size, more simultaneous aircraft and less cross-wind interference. 

Is he crazy? I don't know. I'm sure some think he is. Will this ever happen? I don't know. 

But I do know that, once again, I've found that there is always room for out of the box creative thinking, no matter what. 

If you feel like you're staring at a runway problem, remember Henk.
