Mayor Cherelle Parker said five people are still hospitalized following a fatal medical jet crash in Northeast Philadelphia, three of whom are in critical condition.

The black box was discovered eight feet underground at the crash site after a two-day search and is in “decent shape,” according to reports.

NTSB investigators found the Learjet 55's cockpit voice recorder Sunday. The agency said it was 8 feet down at the site of initial impact. The death toll is 7, with 22 injured.
