13 planes vanish from radars over Europe
An air-safety investigation has been launched after 13 planes flying over Europe disappeared from radar screens in two “unprecedented” blackouts, leading to reports stating air traffic control systems had been hacked. The aircraft went missing from screens across the region in early June, leaving air traffic controllers with no information about their position, direction and height – instead relying on voice communication alone.
