The UPS cargo plane that crashed in Louisville Tuesday was 34 years old and was very recently grounded for more than a month for critical repairs to its fuel tank, according to a report. The MD-11 plane was stranded in San Antonio from Sept.

The three plaintiffs say the companies were negligent in the crash and are seeking damages for residents within five miles.

U.S. federal safety investigators have located the “black box” recorders from the wreckage of a Hawaii-bound UPS cargo plane that crashed in flames on takeoff from the airport at Louisville, Kentucky,

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

Surveillance footage showed the left engine of the UPS cargo plane that crashed on Tuesday in Kentucky, detached from the wing, an official said.
