Seriously, I hope that doesn't mess up his plans/schedule ,although better safe than sorry.
Apparently he was getting info from another guy travelling from here to Madison, WI via O'Hare.
The guy had a brother who had left earlier to go thru Chicago.
(Brothers, like John, had returned to Ohio this weekend for a wedding....and all were communicating via cell-phone)
Any way, the 3rd guy was stuck in a plane on a runway for HOURS at O'Hare...
John and the other brother were MUCH better off just waiting in the airport here.
