TC I am so bad with helicopters.
For Graeme, when he wakes up: I tested goooogling my Chinese challenge to see if it could have been found with the clues I gave, and it is. An additional clue for that (and I have used the technique often): GoogleTranslate is your friend, also when you wish to gooogle other than latin alphabets. And, BTW, GT is much better than its reputation if one wants to have a gist of what is going on and not necessarily an accurate translation. It helps if you know (several) other languages than English because then you may be able to figure out why some translations look stupid (like knowing that in German the verb tends to go to the end of the sentence, and similar features in other languages). GT is not so good in figuring out long sentences fully.
