Families of the victims of a mid-air crash between a helicopter and a plane have visited the site of the wreckage.
Two people in each aircraft were killed in Friday’s crash at Waddesdon Estate, near Aylesbury in Buckinghamshire. There were no survivors.
Thames Valley Police said all four were men. Capt Mike Green was in the helicopter, the BBC understands.
His friend Capt Phil Croucher said he was a “respected helicopter instructor who will be remembered with affection”.
