Two men have been killed after a light aircraft crashed into a field in a rural area a few miles from Chelmsford.
Emergency services were alerted to a major incident at around 2.55pm that a plane had gone down in a field between Ongar and Writtle in Essex.
Essex Police said the Yak 52 aircraft's pilot and passenger, both from Essex, were killed after the plane flew out from North Weald airfield.
A spokeswoman said: "Two people have died after a YAK 52 light aircraft was seen to be in difficulties and then crashed into a field off the A414 near Cooksmill Green between Writtle and Ongar around 2.55pm.".
The spokeswoman said that officers were in the process of locating and informing next of kin.
Firefighters from nearby Chelmsford, Colchester and Maldon are believed to have attended the scene.
The aircraft was "completely alight" when firefighters arrived at the scene near Cooksmill Green, Essex Fire and Rescue Service said.
A spokesman said: "On arrival the incident commander reported that the plane was completely alight. Crews used foam and had extinguished the fire by 3.55pm."
An Air Accidents Investigation Branch (AAIB) spokesman said: "The Air Accidents Investigation Branch have sent a team to investigate."
An East of England Ambulance Service spokesman said: "The ambulance service was called at 2.55pm today, dispatching an ambulance, three paramedic officers, the hazardous area response team (HART) and Magpas helimedics.
"Despite the best efforts of crews the casualties were sadly pronounced dead at the scene. Ambulance resources have now been stood down."
Two people were killed when a Yak 52 aircraft from North Weald crashed in April 2011.
Instructor Simon Hulme, 33, and his 43-year-old student Spencer Bennett, were killed when their plane crashed near Langford, east of Chelmsford.
An inquest in Chelmsford in 2012 heard they were on the last day of a three-day formation flying school when the aircraft span and plummeted from 1,800 ft into a lake.
The jury returned verdicts of accidental death after hearing nearly two hours of evidence.
