I think it's safe to call it that GAF891 is headed to Buenos Aires. It's mich further East that PR-EUF was earlier today.
It should be on the ground in about 50 minutes to an hour.
I suspect that this could be Merkel, as a lot of ex-pat Germans and fugitives from the end of WW2 are located there.
TC-IST went to Sarajevo today and I suspect that this was Erdogan or at least his second in command. It's on the return trip now.
