Co-pilot's friend describes hearing audio of her last moments

A longtime friend of the co-pilot who died in a Florida plane crash on Sunday said air traffic control audio revealing her final moments "was definitely, probably the worst thing I've ever heard."
The co-pilot, 20-year-old Nathalia Filgueiras, can be heard saying in the audio recordings that the jet she was flying alongside 55-year-old captain Jeffrey Gregory was rapidly descending.
"722 Bravo Delta, we're descending 8000 Mayday, Mayday, we're descending 10,000 ft per minute," Filgueiras said.
