Interesting. I had never noticed that before.
The "th" digraph is difficult to pronounce for non-native English speakers, and a lot of them seem to pronounce "three" as 'tree", so that may help the case
Have you been to airports or do you know of airports where English is not the prevalent language, but where they will switch to English for "foreign pilots?
