The black box from the Boeing jet that crashed and killed all 157 people on board will be sent overseas for analysis but no country has been chosen, an Ethiopian Airlines spokesperson said on Wednesday, as much of the world grounded or barred the plane model and grieving families arrived at the disaster site.

In an interview with The Associated Press, Asrat Begashaw said the airline has “a range of options” for the data and voice records of the flight’s last moments. “What we can say is we don’t have the capability to probe it here in Ethiopia,” he said.

The Boeing 737 Max 8 aircraft crashed shortly after takeoff on Sunday, killing all 157 people on board. The disaster is the second with a Max 8 plane in just five months.

While some aviation experts have warned against drawing conclusions until more information on the latest crash emerges, much of the world, including the entire European Union, has grounded the Boeing jetliner or banned it from their airspace.
