It's untrue.
Kalitta was not banned from the EU, or from any other location. Following the Brussels loss (and Bogota), Kalitta was investigated by the FAA, by EU authorities, and by the US Department of Defense...and came up clean.
Kalitta is not banned from the EU, and any rumors to that effect are false.
It's an old rumor too, by the way...one put to bed some time ago.
