Drones in four near-misses at major UK airports, air investigators reveal

Pilots call for action and warn the four category-A incidents at Heathrow, Stansted, City airport and Manchester are just the tip of the iceberg

Airline pilots have called for a clampdown on drones, warning of potential disaster after four separate near-miss incidents at UK airports were reported in a single month, including one in a passenger jet taking off from London Stansted.

The pilots have called for urgent action after the four "category A" incidents in which a serious risk of a collision occurred.
