 WBT AM Charlotte. WBT FM Chester. WLNK HD2 Charlotte. News Talk 1110 and 99.3 WBT. Good evening. I'm Anna Erickson in the WBT News Center. A global computer crash on Microsoft Business Systems still causing air travel headaches at Charlotte Douglas. Chaos. Just mass chaos. All the flights were canceled. There's no rental cars. Everybody's just trying to get to where they're going. They just basically told us there was no way we were getting out of here today.
