In the aftermath of a tragic plane crash in Louisville, Kentucky, that resulted in at least 14 confirmed deaths and several individuals still missing, UPS and FedEx have grounded their fleets of MD-11 aircraft. Investigators from the NTSB are probing the incident, which involved the sound of a persistent bell in the cockpit before the crash. Eyewitness accounts and dramatic footage reveal the aircraft bursting into flames upon takeoff, with tragic losses among the victims, including a grandfather and his young granddaughter. The call for grounding comes as Boeing advises similar actions to ensure safety as the investigation continues.
