The “black box” data recorders recovered from Ethiopian Airlines Flight 302 will “definitely be going to Europe”, though they haven’t decided which country yet, says airline spokesman Asrat Begashaw to CNN.

A decision on exactly where the “black box” will go is expected Wednesday night or Thursday, Begashaw added.

When pressed about which “black box” or if he meant both black-box recorders, the Ethiopia Airlines spokesman did not differentiate between the two. Both the Digital Flight Data Recorder (DFDR) and the Cockpit Voice Recovered (CVR) were recovered at the start of the week, the airlines said in a statement issued Monday.

Ethiopian Airlines CEO Tewolde GebreMariam told CNN’s Richard Quest on Tuesday that Ethiopia's Ministry of Transport would work with the United States, where Boeing is based, to find a place outside the country to examine the black-box data. Ethiopia does not have the necessary equipment to perform those tasks on its own, GebreMariam added.

The nature of the black-box recorders cannot be overstated, says CNN’s Richard Quest. "The single most impart part of the investigation at the moment is the black boxes, because they have the answer to what happened."

Quest also highlights that Ethiopian Airlines have not yet spoken out about the condition of the black boxes.
