i was actually at ord just after this took place. i was listening to ground control and noted that everyone sounded a bit stressed and everything was very backed up. i dismissed it as a regular busy friday night until i got to my hotel and saw the 9pm wgn news…wow! it sounds like the beds worked very well…it must have been a bumpy ride though!
