Drone near-misses prompt calls for plane strike research - BBC News
Pilots are calling for research into what would happen if a drone hit an airliner, after 23 near-misses around UK airports in six months last year.
Reports from the UK Airprox Board reveal the incidents happened between 11 April and 4 October 2015.
In one incident a drone passed within 25m (82ft) of a Boeing 777 near London Heathrow Airport.
Pilots union Balpa wants the government and safety regulator to back research into how serious a strike could be.
The incident at Heathrow was one of 12 that were given an "A" rating by the independent board, meaning there was "a serious risk of collision". It is the most serious risk rating out of five.
Other incidents given the most serious rating include a drone coming within 20m (66ft) of a Embraer 170 jet on its approach to London City Airport above the Houses of Parliament on 13 September.
