Two people have died in a light aircraft crash on the Queen's Sandringham Estate in Norfolk.
The pilot, in his 50s, and a female passenger in her 70s, died when the Piper PA-28 aircraft came down in marshland near Wolferton at about 11:00 BST on Monday.
They were pronounced dead at the scene, Norfolk Police said. There were no other casualties.
The Air Accidents Investigation Branch (AAIB) is investigating.
The BBC understands the two people who died in the crash do not have connections with the royal family or the military.
The village of Wolferton lies within the Sandringham Estate and is about seven miles (11km) north of King's Lynn, near the north Norfolk coast.
Emergency services including police, Coastguard, Norfolk Fire and Rescue Service, the East of England Ambulance Service and the air ambulance were called to the scene.
Steer Road leading out of the village was blocked off by police, who were at the scene working with officials from the AAIB, and later re-opened.
An AAIB spokesman said the aircraft would be taken to "our facility in Farnborough where a detailed examination can take place while our investigation continues."
The wreckage of the blue and white plane was removed from just behind the sea wall shortly before 20:00 BST.
