A merican delivery firm UPS has temporarily grounded part of its fleet of cargo planes after a mid-takeoff crash in Kentucky on Tuesday left at least 14 people dead.

One of the casualties of a fiery plane crash in Louisville worked at Wright-Patterson Air Force Base. UPS issued a statement regarding the people killed in the plane crash Tuesday evening. “It’s with great sorrow that we share the names of the UPS pilots on board UPS Flight 2976.

Investigators say a repeating bell sounded as pilots tried to control a UPS cargo plane upon takeoff before it crashed in Louisville, Kentucky, this week.

"If you see oil, debris, or discoloration in a waterway, please report it by calling 502-540-6000," Louisville MSD said.

Video of the deadly Louisville, Kentucky, crash showed flames on one of the plane's wings and a huge fireball erupting as the aircraft hit the ground.

The grim task of finding victims from the firestorm that followed the crash of a UPS cargo plane in Louisville, Kentucky, has entered a third day.

At least 12 people were killed and several others injured after a UPS plane crashed shortly after taking off from the Louisville International Airport on Tuesday.
