The black box containing information regarding the plane crash in Gaithersburg, Maryland, has been recovered by National Transportation Safety Board (NTSB) investigators. Monday's (Dec. 8, 2014) crash left six people dead, including two small children, in the suburb of Washington, D.C. The black box contains the cockpit voice recorder and the flight data recorder. Investigators also are reviewing a series of 911 calls that came in after the twin-engine Embraer EMB-500/Phenom 100 reportedly broke into pieces with fuselage crashing into a house and debris hitting two other adjacent homes on the cul-de-sac that also went up in flames. Senior Investigator Timothy LeBaron is leading the NTSB team at the scene. Some witnesses told the press they heard a "sputtering" before the plane went down. CNN is reporting that one of the persons aboard was Michael Rosenberg, CEO of a clinical development company who also happened to be a pilot. It is not yet known if that person was piloting this executive jet that has heading from Chapel Hill, North Carolina, to Gaithersburg. Mr. Rosenberg was certified to fly that type of aircraft, according to Federal Aviation Administration (FAA) records. He also had a close call at that same airport in Maryland in 2010 when he was piloting a plane that left the runway, but he walked away from that incident, according to several media reports.
