Investigators look into 'repeating bell' heard during takeoff of UPS cargo plane that crashed

LOUISVILLE, Ky. (AP) — A repeating bell sounded in the cockpit for 25 seconds as pilots tried to control a UPS cargo plane that caught fire, had an engine fall off and crashed during takeoff this week in Louisville, Kentucky, a National Transportation Safety Board member said Friday.

The cockpit voice recorder captured a persistent bell that began about 37 seconds after the crew called for takeoff thrust, and the bell continued until the recording ended, which investigators believe was the final point of impact, NTSB member Todd Inman said.
