The engine of a UPS jet that exploded in a ball of fire in Kentucky fell off the aircraft during takeoff, officials revealed while confirming the fiery death toll had reached 12 in an “apocalyptic” scene that looked like something out of “Terminator.”

“We have viewed airport CCTV security coverage, which shows the left engine detaching from the wing during the takeoff roll,” National Transportation Safety Board (NTSB) Member Todd Inman said at a Wednesday news conference.

The footage reviewed by the NTSB has not been released, but clips that have been circulating show UPS Flight 2976’s left engine engulfed in flames as it skidded across the tarmac like a flaming bullet at Louisville’s Muhammad Ali International Airport just after 5 p.m. Tuesday.

Moments later the aircraft collapsed into the ground and burst into flames, killing all three crew members on board and at least eight people – including possibly one child.

“We believe that we will learn that there was one child in those 11 and a young child at that which makes it all the harder,” Gov. Andy Beshear told reporters.

“We do not expect to find anyone else alive in the area,” he told reporters, adding that the operation had moved from rescue to recovery mode.

The plane’s black box has also been recovered, the NTSB said.

Flight 2976 slammed into the grounds of a petroleum recycling center and an auto salvage yard located near the runway – with the petroleum facility’s materiel bursting into a towering inferno that raged for hours and incinerated the grounds.

“Where the plane hit, at best, is destroyed. What you see are mangled remnants of what was in its path completely burned and blackened,” Gov. Beshear said after visiting the site.

Most of the deaths happened at the auto salvage yard, which was also largely destroyed, officials said.

All workers at the petroleum facility had clocked out before the crash and nobody there was hurt – except for a beloved shop cat named Bob, who hasn’t been seen since.

Stunning dash cam footage showed the plane flipping as it failed to stay airborne and slammed into the ground with a wall of flames that engulfed a lot filled with container trucks – some of which were devoured by the fire.

“Ohhh s—t!” a driver seated near the explosion in one of those trucks as his face lit up from the flames. “Oh my f—king god!”

Another clip captured people fleeing for cover as flames roared into the sky, with a burst of blue and green fire following with a hiss as something in the petroleum facility apparently exploded.

“The skies over Louisville looked apocalyptic last night. People scared all over our community, debris falling, ash falling, people sheltering in place,” Kentucky Rep. Morgan McGarvey said after Beshear spoke.

“It was like a scene out of a ‘Terminator’ movie,” he added.
