Well, well, well, look what I found. This plane says "Republica Argentina" and doesn't belong to an airline. This is the presidential plane, called Tango 01, the T-01. ("Tango" is the name for the letter T in aeronautic language. It was chosen as the most known word at the moment beginning with the letter "T". Since tango is from here the presidential plane was called Tango 01)
