Prince William, the future king of England, announced in January that he will stop piloting a helicopter for an air ambulance charity this summer so he can spend more time with his children in London.
Whether a near-collision of the helicopter he regularly pilots and a drone above London last summer played a role in that decision is something only William — and maybe the Duchess of Cambridge — knows. This is not the sort of thing you tell your grandma.
According to a report by the UK Airprox Board, a four-bladed quadcopter drone 1,900 feet above London passed within 30 meters (98 feet) of a Eurocopter 145 helicopter carrying a pilot and multiple medical crew members on Aug. 26.
