 Preliminary information indicates at least three people were on board and didn't survive the Monday crash into home in Gaithersburg, a Washington, D.C. suburb, said Pete Piringer, a Montgomery County Fire and Rescue spokesman. 
  
 He said a fourth person may have been aboard. 
  
 Piringer said the jet crashed into one home around 11 a.m., setting it and two others on fire. Crews had the fire under control within an hour and were searching for anyone who may have been in the homes. 
  
 Television news footage of the scene showed one home nearly destroyed, with a car in the driveway. Witnesses told television news crews that they saw the airplane appear to struggle to maintain altitude before going into a nosedive and crashing.

 GAITHERSBURG, Md. (WUSA9) -- The investigations into a plane crash that left six people dead in Gaithersburg on Monday evening are just beginning. 
  
 A mother and her two young children are three of the six lives lost in the crash.

 Three people on the jet were also killed, according to Montgomery County fire officials. One of those victims has been identified as Michael Rosenberg, CEO of Health Decisions. You can read their statement here. 
  
 An Embraer EMB-500/Phenom 100 crashed into a house in the 19700 block of Drop Forge Lane off Snouffer School Road in the neighborhood of Hunters Woods around 10:45 a.m., according to the NTSB. The plane was coming from Chapel Hill, NC and approaching the Montgomery County Air Park. 
  
 The NTSB has sent a go-team to the site, where three homes were damaged. Firefighters used foam to battle fires all around the scene. The fuselage of the jet is parallel to a second house, and the tail of the airplane is at the front door. One of the wings was catapulted into the Gemmell's house, causing a huge fire and the majority of the damage, according to the NTSB. Senior Investigator Timothy LeBaron is leading the go-team. 
  
 Investigators are looking at operations, including crew experience, training and procedures, the functionality of the engines, the weather, air traffic control and more, NTSB spokesperson Robert L. Sumwalt said at a press confrence. 
  
 "Our mission is to find out not only what happened, but why it happened because we want to make sure something like this never happens again," Sumwalt said.

 NTSB investigators are currently collecting perishable evidence, not determining the cause. They'll be conducting interviews and documenting the wreckage. Investigators could be on the scene for three to seven days for what they call the "fact-finding" phase. 
  
 The black box, which has recordings from the crash, has been recovered. It is in good condition and has been rushed to labs, Sumwalt said. 
  
 The first call about the crash came in at 10:44 a.m. from the National Guard Armory for the report of an explosion, and units were on the scene in approximately seven minutes, Montgomery County Fire Chief Steve Lohr said at an initial press conference. Utility crews were also on the scene and Lorh said it is safe for residents in the area. Electricity has been temporarily cut off. 
  
 Recordings of the 911-calls from the crash were released on Monday evening. In the recordings neighbors and witnesses describe the scene where the plane crashed in the Gaithersburg neighborhood. 
  
 Recordings of the 911 calls from the Gaithersburg plane crash were released on Monday evening. 
  
 "We just heard a giant explosion we looked out the window and there's... it looks like a house is on fire, we've got some people running over there to see if people are okay," one caller described. 
  
  
  
 RAW: Fire Chief Steve Lohr speaks on plane crash 
  
 A woman who was traveling into the area after taking a test at Montgomery College tells WUSA9 that she could see the smoke from the crash from I-370. As she got closer, she saw all the emergency response vehicles and called her husband. He told her that the smoke was coming from the area where her mother and stepfather lived and she says she got worried. She discovered the house that was struck was their neighbors' house. She says there are "three little ones" who live in that house. 
  
 One person reported seeing the plane "wobble" before it crashed into the house. Other neighbors reported hearing repeated booms and feeling their houses shake from the impact of the plane. 
  
 Something went wrong with the jet heading to the Montgomery County airport and it went into a house in Gaithersburg 
  
 WUSA9 spoke with an eyewitness named Jocelyn Brown who said she first heard the plane sputtering, making a sound that planes that go over the area normally don't make flying over the houses. She says she and her mother became concerned and went to investigate. They then saw the plane hit the side of a house. She reported seeing a "mushroom effect of smoke" and also hearing three explosions after the plane hit. 
  
 Jocelyn says they also heard screams in the area of the home. She says she does not know whether they were coming from inside the house or behind them. 
  
 Jocelyn lives in the area and says she knows the mother that lives there. She described her as a "sweet woman" who walks with her kids in the area all the time and speaks to everyone. 
  
 He said the plane sounded like it was "puttering" and then saw fire 
  
 A woman posted video from the ground of the scene of the plane crash on YouTube.

 The FAA has released the following information: 
  
 "This is preliminary information about an Embraer EMB-500/Phenom 100 twin-engine jet that crashed one mile north of the Montgomery County Airport, Gaithersburg, MD at 11am today. The aircraft was on approach to Runway 14 at the airport when the accident occurred. Please contact local authorities for information on passengers and the situation on the ground. The FAA will investigate. We will update this statement when new information is available. "

 An FAA source says the jet was waiting for a much slower single engine aircraft, possibly a Cessna, to make its turn so it could make its approach. That information has not been confirmed by the NTSB. 
  
 The Montgomery County Air Park is within 1/2 to 3/4 of a mile of the crash. The airport does not have a tower, so communication would have been with Washington Air Traffic Control Section, not the airport. 
  
 The FAA registry shows that the plane was a corporate Phenom jet with tail number N100EQ. It's registered to Sage Aviation LLC out of Chapel Hill, NC which makes replacement parts for the aviation industry.

 Snouffer School Road was closed between Centerway Road and Goshen Road following the crash. Drivers and pedestrians are being urged to avoid the area. It is likely to remain closed throughout the night and possibly Tuesday. 
  
 She says something has to be done about planes flying low directly over homes.

A twin-engine Embraer jet that the FAA describes as "on approach to Runway 14" at the Montgomery County Airpark in Gaithersburg, Maryland, crashed into a home this morning, engulfing that home in flames and setting two others on fire. Three people are dead, but the count could grow. A Montgomery County Fire rep says three fliers were killed in the crash, but notes the corporate plane may have had a fourth person on board, reports the AP. A relative of the owner of the home that was hit tells WUSA 9 that a mother with three children pre-school age and under should have been home at the time; there's no word on the family's whereabouts. The crash occurred around 11am on Drop Forge Lane, and the fire was extinguished within an hour. Crews are now searching the wreckage. A witness noted the plane appeared to "wobble" before the crash; the airport is no more than 3/4 mile from the crash scene. NTSB and FAA will investigate.
