Two crew members have been killed after two helicopters collided mid-air in Greece while battling wildfires. The fatalities were a Danish pilot and a Greek fire service liaison officer. A British pilot and another Greek co-ordinator on the second helicopter survived. The crew members of one aircraft were rescued alive, while the second crew were recovered unconscious and later pronounced dead. In a post on X, he said the loss of the Greek coordinator and Danish pilot "fills us all with grief".
