This could have almost certainly been a major disaster in Barcelona’s aviation history. The incident happened between UTair Boeing 767-300 and Aerolíneas Argentinas Airbus A340-300. The UTair jet was in its final approach and was about to land when they spotted the Aerolíneas aircraft crossing the runway. The UTair pilots had to abort the landing and take a go around. Must say this was truly risky albeit live saving maneuver by the UTair pilots.
