A jetliner preparing for take-off at Rome's Leonardo da Vinci airport has nearly collided with an airliner which was set to land on the same runaway.
None of the 200 passengers on board the two flights were injured in the near-collision, said the Italian air traffic controllers' association, Enav.
The Eurofly jet was preparing for takeoff when it strayed from its designated runway and entered the taxiing area of the Alitalia MD-80 landing from Bucharest, Romania.
Air traffic controllers noticed the mistake and guided the Eurofly jet back onto the correct runway without incident, said Enav.
Eurofly is Alitalia's charter airline.
The error was similar to the mistake that resulted in the deadly crash at Milan's Linate airport in October, when an SAS airliner collided with a business jet that crossed its path.
The crash, Italy's worst aviation disaster, killed 118 people.
