WACO, Texas (KWTX) - A U.S. ground stop delayed the return of about 45 members of the Greater Waco Chamber of Commerce who were on a plane in Costa Rica preparing for takeoff."We were supposed to leave yesterday, at 3:30, once we were on the tarmac and we were in line to take off, that's when the pilot notified everyone on the plane there were some issues with air control traffic," chamber board member Hector Sabido told KWTX.

After getting off the plane, they were told their flight would leave at 5 p.m., then 7 p.m. By 9 p.m., they learned they would not leave that night."We found out 'hey, your flight is not going to take off tonight after all, so come get your luggage and come back tomorrow,'" Sabido said.

"It was very spontaneous, not planned and we just had to look for sleeping arrangements."Sabido said they stayed in groups at local hotels.
