One of the four people killed in a collision between a helicopter and a small plane has been named.
Captain Mike Green was flying the two-seater helicopter which collided with a Cessna 152, a light two-seater aircraft.
Green was, according to Sky News, a senior instructor with more than 30 years of flying experience.
He was a member of the Helicopter Services team based at Wycombe Air Field in Buckinghamshire.
The company said on Facebook: “We are devastated to confirm that Captain Mike Green was involved in the mid-air collision which occurred yesterday.
“Mike was conducting a flight instructor course and was with a student at the time of the incident. Both pilots lost their lives.
“We have received many messages of support and kind words about our friend who, as a senior instructor and examiner, helped and mentored so many pilots throughout the industry during his distinguished career.
“It was an honour to work with you. Captain Green, you will be greatly missed.”
Captain Phil Croucher, who had known Mr Green for around 20 years after they had served in the Army together, said his death was a “sad loss”, the Press Association reports.
The crash happened over dense woodland near the historic Waddesdon Manor in Upper Winchendon, near Aylesbury at around midday on Friday.
Two people were aboard each aircraft, Thames Valley Police Superintendent Rebecca Mears said at a press conference on Friday evening.
Investigations are underway into the cause of the crash.
