Thanks for the "causality" pointer.
I found CycL "#$causes-PropProp",
which is essentially the same as MKR "causes".

For planning, I didn't find anything that seemed right,
so I made up my own "CycL predicate": "create-plan".

If you now click on the HowAirport.html and WhyChicken.html
links below, you will see the "final" MKR scripts.
I am going to feed these to OpenCyc and see what happens.
