A plane approaching Heathrow Airport is believed to have hit a drone before it landed safely, the Metropolitan Police has said. The British Airways flight from Geneva was hit as it approached the London airport at about 12:50 BST with 132 passengers and five crew on board. After landing, the pilot reported an object - believed to be a drone - had struck the front of the Airbus A320. Aviation police based at Heathrow have launched an investigation. Police said no arrests have been made. If confirmed, it is believed to be the first incident of its kind in the UK. A British Airways spokesman said: "Our aircraft landed safely, was fully examined by our engineers and it was cleared to operate its next flight." The airline will give the police "every assistance with their investigation", the spokesman added.
