According to local news 3 flight in FWA where grounded due to a "threat" of some sort, apparently non-terrorism. It appears as though from the destination that the flights had that they where DL (CVG), NW (DTW), and AA/TZ/UA (all they said was Chicago). Does anyone have any other information on this?
That's the only news source I can find with information, and it's from SBN, the local FWA station is not reporting anything, as of yet.
(Please note that the picture in that story is actually a Comair CRJ in SBN, not FWA)
