The company which owns Spain’s Air Europa airline says the pilot that set off an accidental hijacking warning in Amsterdam�s Schiphol Airport was teaching procedures to a junior pilot at the time.

Globalia said Thursday the pilot keyed in the code by mistake as the plane bound for Madrid was preparing for takeoff Wednesday.

The alert triggered a big security operation at the airport. No one was injured.

The company said in a statement Wednesday that the passengers informed by the crew that it had been a false alarm.

The airline tweeted at the time: �Nothing has happened, all passengers are safe and sound waiting to fly soon. We deeply apologize.�

Globalia said Thursday it considered the matter finished and no disciplinary action would be taken.
