Four people have died after a helicopter and light aircraft were involved in a mid-air crash in Buckinghamshire, police have confirmed.
Both aircraft are understood to have flown from Wycombe Air Park and collided near Waddesdon, in Buckinghamshire, shortly after midday.
Thames Valley Police Superintendent Rebecca Mears said officers were now tracing the victims’ families.
She said she could not identify the victims at this stage and her “first priority” was their next of kin.
Ms Mears said: “Our priorities today remain with investigating the next of kin, finding out who they are, informing them and supporting them with specialist officers as we progress the investigation here on site.
“Our priority has to be with the next of kin, speaking to them and letting them know.
“We anticipate being here until about Monday morning, potentially longer, we do not rush these things, it’s really important we do a meticulous investigation and really thorough to get to the bottom of what’s happened here.”
Police said there were two people on board both aircraft, and it was “too early to tell” what might have caused the crash.
A Notice to Airmen was previously issued to warn pilots the Wycombe Air Park’s air traffic control services would be closed during three 30-minute periods on selected days between 7 and 30 November due to a “staff shortage”.
The crash occurred around half an hour after the latest closure was due to end.
