ATC watcher:
Fully agree with your questions concerning A 320 involved. Have still no access to any statement by mexican officials but it seems that language problems refering to the duty managers statement
are not likely. If there is a "mexican version" of the story I would enjoy any enlightment.
Did not talk to the crew myself but I have information that the conversation between crew and duty manager was conducted in plain clear english.
As RatherBeFlying states the quote "do not follow TCAS commands"( in the approach sector to MEX) is original and as I understand varified by the BFU.
Thank you for your replies.
Regards
