HENRICO COUNTY, Va. (WRIC) -- Friday's nationwide ground stop threw passengers at Richmond International Airport (RIC) into a tailspin, impacting a dozen flights. "I was concerned about all the pilots and the passengers in the air, hoping that they get home safely and get grounded safely," Ken Ston er, who was flying to Florida for a cruise, told 8News. RIC saw many cancellations and delays after the FAA grounded flights around 4 p.m. on Friday, Nov. 13, due to what was initially described as communication issues. "I was just thinking, 'This is going to be a long night,'" said Gavin Firschein, who was heading to Connecticut. "I asked 'Why?' and got dismissed," added Lamar Palmer, who was flying to Florida to celebrate his daughter's 21st birthday. One grounded flight left several passengers, originally en route from Boston to Atlanta, stranded in Richmond. Some passengers at RIC asked whether the groundings were related to Microsoft's outage from Thursday. However, Department of Homeland Security Secretary Markwayne Mullin said there's no connection. The FAA lifted the ground stop after about four hours. During that time, travelers caught themselves scratching their heads or calling their loved ones on the phone about what to do next. "I just feel like they should, probably, be giving us a little bit more information on what's going on," Palmer said. "We're trying to decide whether to walk in and wait for it or leave," Stoner added. Others also weighed whether they should rent a car, head home or stick it out and hope flights would take off sooner as opposed to later. "I think I'm going to be sticking around here just in case," Firschein said. It will take time to get all flights back in motion, according to federal officials. Some flights will be able to take off tonight, while others may need to wait until Saturday morning. In the meantime, federal resources have been activated to help flyers who are in a bind due to the ground stop. When asked what caused the disruption, federal officials said outdated infrastructure was to blame. They continue to investigate. ...read more read less
