NTSB investigators have recovered the engines and cockpit voice recorder (CVR) of the Learjet 55 that crashed on Jan. 31 in Philadelphia, killing at least seven people.

However, a Saturday morning update from the Philadelphia mayor's office confirmed that all six people aboard the plane had died. The statement noted that many people on the ground "in parking lots, on streets, in cars and homes in the area" were injured, but the number of injured people "is yet to be released."
