PICTURED: Horrifying moment engine flies off before UPS cargo plane crash that killed 14 people

The six photographs also showed the rear section gradually detaching from the aircraft.

Flames then rise above one of its wings, with the blast becoming more and more ferocious.

The final image captured the moment the UPS aircraft continued with its attempted take-off.

However, the MD-11 plane only managed to climb some 30 feet from the ground.

The plane quickly slammed into the ground, tearing a hole through the roof of a UPS warehouse,

It then exploded into a fireball at the airport.

Flight data had already featured in a preliminary probe conducted shortly after the crash in Louisville, Kentucky, on November 4.

The aircraft was scheduled to leave Louisville for the Daniel K Inouye International Airport in Honolulu, Hawaii.

Three pilots died and a further 11 individuals on the ground close to Muhammad Ali International Airport were also killed.

The National Transportation Safety Board confirmed the UPS aircraft had not yet scheduled a thorough inspection of crucial engine mount components.

The aircraft instead required nearly 7,000 additional take-offs and landings before facing an inspection.

However, the most recent examination took place in October 2021, some 48 months ago.

"It appears UPS was conducting this maintenance within the required time frame, but I'm sure the FAA is now going to ponder whether that time frame is adequate," former federal crash investigator Jeff Guzzetti said after the release of the report.

John Cox, another aviation expert, simply characterised fatigue cracks as "normal wear and tear on an aircraft".

Meanwhile, Bill Moore, president of UPS Airlines, an arm of UPS, said the company is working with investigators to determine the “root cause” of the crash.

“Once we determine that, then they’ll be able to develop an inspection plan,” Moore said at a news conference in Louisville.

“Can we inspect it? If so, how do we repair it? How do we put it back together?

"And then eventually return the fleet to service. But that’s not going to happen quickly.”

UPS has since announced it has grounded its fleet of MD-11s.

The American multinational shipping and logistics company will use other aircraft during the upcoming festive period.

The NTSB noted in its report that a similar crash involving this type of plane killed over 270 people in Chicago in 1979.

American Airlines Flight 191 crashed into an open field after the left engine and pylon assembly and part of the left wing separated from the plane during takeoff, the report said.
