would it have killed the atc to just have the Cargolux 747 wait on the runway while the A319 was landing? I've always wondered about the dangers of crossing runways when aircraft go around
The dangers exists and have been, according the FAA " mitigated " . Therefore you have more niceties in the US , like allowing Land and Hold Short procedures on intersecting runways .( US ALPA is supporting this , even against IFALPA recommendation btw)
The argument in there is expedition ( i.e landing/departing more aircraft per airport at any given time ) and unfortunately not safety first.
As to the argument old versus kid pilots, I 've seen so many incidents now where kids were trying to fix or please the computers instead of manning the shop that I tend to agree wholehearthly with 3 green in there ....
