OK...here it is, I'm going to say it out loud, (and probably get flamed for it) but I don't care as it has become dangerous. In my area of the globe (Phoenix, AZ) we have some of the best year-round weather for flying. Many flight school students from around the world travel here to take advantage of it and that is cool. What has become a problem though is not being able to understand transmissions that are in very bad broken English. Part of everyone's safety up there is to be able to listen (especially at a busy field) and paint a mental picture of where everyone is at. I'm sure others have dealt with this no matter what part of the world they live in, but for here it can be a daily event. It sure is concerning and has given more than one pilot a close call.
