According to a UK Airprox Board report, a “DJI Mavic type” drone was spotted by a London City airliner right after taking off. The drone was spotted at approximately 3,000 feet elevation above Stratford, as the De Havilland Dash-8 turboprop airliner had just taken off from London City Airport.
The UK Airprox Board report is unusual as typically the type of drone is not specified. This time the “DJI Mavic type” drone was seen by the third pilot in the observer’s position. According to the same report, it was ‘endangering other aircraft’.
