Key locations in the mid-air collision between a helicopter and an aircraft

An aircraft and helicopter collided in mid-air northwest of London on Friday and a "number of casualties" were reported, authorities said.

It happened near the historic Waddesdon Manor estate and several people are feared dead, according to reports. "We can now sadly confirm that four people have died at the scene".

Witnesses told the Mail Online they heard a big bang, saying: "My father heard a loud bang".

Emergency services are now at the scene near the village of Waddesdon, which is home to Waddesdon Manor.

The Air Accidents Investigation Branch, the AAIB, has been informed and their staff have been on the scene.

A spokeswoman said: "We received the call at 12.09pm, for a mid-air collision involving a helicopter and an aircraft in Upper Winchendon, near Aylesbury". Fire and ambulance services are also in attendance and preservation of life is first priority.

"We sent various assets to the scene, including the Thames Valley air emergency vehicle, two rescue vehicle groups, two rescue vehicle officers, and a quick reaction vehicle", said a representative.

Road disruptions around Waddeson are expected for the rest of the day.

Wreckage from the aircraft tumbled from the sky and landed less than 2km from the former home of the Rothschild banking family at Waddesdon Manor in Buckinghamshire, at lunchtime yesterday.

RAF Halton - around 10 miles away - says no military aircraft were involved.

It boasts 6,000 acres of farm and woodland and is one of the National Trust's most visited properties, with over 390,000 visitors every year.
