The proper measure is not how many pilots are irrated by those damn Yanks and their non standard phraseology. Its how many incidents/accidents ahve occured. The way its played out by the Euros, US planes should be falling out of the sky. Simply not happening. That along with our far inferior pilot training in both the civilian and mil sectors, its amazing little johnny makes it to grandma's house on the airlines.
I always find it amazing to listen to the pompous arses here talk about US RT and then listen to Speedbird crossing the US and hear the same slang we are accused of. I guess the pack comes off when no other nigel can hear them.
