Aerolineas Argentinas A340-313X, LV-FPV, (c/n 193) sporting the "Skyteam" color scheme crossed in front of a UT Air 767-306ER, VQ-BSX, (c/n 27612/647) on final approach to Barcelona El Prat Airport's (BCN) Runway 02 on the morning of Saturday, 05Jul14.
While some experts say that it was likely that the A340 would have crossed the runway before the 767-300 reached that point, the 767 still had to abort its approach and perform a go-around to approach and finally land.
The Aerolineas A340 was reportedly following ATC instructions to taxi to Runway 25R so ATC had primary responsibility for the incident but it seems that the first officer sitting on the right side of the aircraft should have seen the approaching 767. The Aerolineas pilots will presumably be interviewed after this incident and it will be interesting to see what they have to say about this serious incident.
