I didn`t include the airlines as I didn`t want to provoke parochial mud slinging, but on reflection it is no slur on the airline and the vast majority of their exemplary crew, merely on this one individual. The "offender" was from South African and the conflicting aircraft was Alitalia. We were very impressed with the way the situation was handled by the Italian crew who refused to be drawn into an R/T based slanging match, treating his repeated haranguing on 126.9 with the contempt it deserved.
