Thanks for the massive red flag warning which I shall disregard.
The information is very useful and thanks for the thorough research. I have just done the latest 747 update without any problem but I still cannot update the operations center after innumerable attempts so it does not seem to be the local server, which is Bluesky Samoa. Anyway as long as the (superb) aircraft continue to update the operations center probably does not matter too much as it seems to bring the latest information and is noted as optional anyway.
My name is Michael Anderson as in manderson.
