Several people are feared dead after a mid-air collision between a helicopter and a plane over Buckinghamshire.

Wreckage from both aircraft is believed to have landed in the estate grounds of Waddesdon Manor, near Aylesbury, on Friday afternoon.

At least seven fire appliances, including three urban search emergency vehicles, were sent to the scene along with six fire officers who also launched the fire brigade drone to look for any survivors, reports The Telegraph.

Staff from the Waddesdon Estate - which is managed by the Rothschild Foundation on behalf of the National Trust - helped direct emergency vehicles to the scene as police erected a large cordon.

Staff from the Air Accident Investigation Branch (AAIB) were also sent to the area, but police said the priority is being placed on saving lives.

Sources said that it was believed there were multiple casualties, including fatalities. Both aircraft came from Wycombe Air Park, near High Wycombe.

A Thames Valley Police spokesman said: ‘Officers are currently at the scene of an air accident near the village of Waddesdon near Aylesbury.

‘The force is coordinating the response to the incident which was reported at 12.06pm today.

‘The Air Accidents Investigation Branch has been informed and staff are en-route to the scene. Fire and ambulance services are also in attendance and preservation of life is first priority.

‘In consequence of this incident it is expected that there will be some disruption to the road network around Waddesdon for the rest of the day.
