Yes there are perhaps a few non-english speaking on RT who because of accents/vocabulary are hard to understand. But, being the standard brit who has a very limited knowledge of second/third language, I am often impressed by those who work in this environment, especially in a non-standard and high stress situation, whilst conversing in a non-native language.
We in the UK, especially in the London TMA, tend to speed up information flow, for obvious reasons, without thought for those who are not native english speakers. In fact there are times when information is passed in such quantity and with such speed that even the native english speakers have to question it again. It's not the end of the world, but some recognision of this should be made.
If communication breaks down completely, then a report should be filed for investigation, which was obviously done in this case. Let's give some credit to the majority of those to who english is the second language (possibly third or fourth) and perform no differently to the you or I. Whilst there has to be a minimum standard we should be giving every assistance to those who are less proficient.
