The mayor of Louisville, Kentucky, took to social media on Friday evening to announce a 14th person who has died after a UPS cargo plane crashed as it was taking off at that city’s airport on Tuesday.

But a cockpit voice recorder picked up a ringing sound during takeoff that may have signaled looming disaster in the crash that killed at least 13 in Louisville, Ky.

The death toll rose to 14 after Mayor Craig Greenberg said another body was found at the crash site. Three UPS crew members on the plane were identified.

Haunting similarities can be found between the UPS jet crash and the deadliest aviation incident in U.S. history, a crash at O'Hare Airport in 1979.
